Great device and even better customer service

X

I have been using Mendi for a while now and honestly it has been quite transformative for me. The biggest thing is that I can now catch myself when I am deep in a thought. It helps me stop, ground myself and come back to the moment.

It even helped me a bit with smoking. I am no longer lighting one after the other without really noticing.

The best way I can put it is this is that it helped me put a pause between the thought and the action. A lot of what I did before was on autopilot. Now, more often than not, I get that small gap where 1 can actually decide what to do.

This showed up in a very specific way with my wife. I used to be quite reactive during conversations, and I have noticed I am much better at pausing bef respond.

To be fair, I do not know if this is all Mendi or partly placebo. I am not saying it will work the same for everyone. I am just sharing my own experience, and for me it worked.

What really stands out though is the customer service. It is pure class. In my first few months I had an issue and they sent me a new headband straight away, no fuss. Then about five years later, the clip that holds the strap broke. It was way past the warranty, and they still sent me a replacement.

Robert is honestly the best customer service person I have ever dealt with. Thanks mate.

Worth a try if you need to develop better focus

So I used the product for approximately 56 days to maximise the 60-day return window. It definitely took about a month to kind of get it to click, and I was getting consistently high scores using it pretty much every day for one session of 10 to 15 minutes.

While I do think it was improving my focus, I did not receive a lot of secondary benefits that a lot of other users with ADHD report, such as better emotional regulation or task initiation. So definitely if your issue is with focus, then this probably will be a game-changing device, but I am a little bit leary with people saying it helps with sleep apnoea and things that are not related to focus because again, this is just training your focus.

The app itself is well done and you have enough functionality I find to make it work, and I do really like the pairing with Brain.fm. The music definitely does help set the tone for how the training session can go.

I will say the company is good with their customer service, a little repetitive in terms of the advice that's offered. It's usually just a cut and paste of have you tried this, have you tried that, but I do understand you keep receiving the same question hundreds of times, you're going to start to develop the same type of answers.

The refund process was pretty straightforward and I did receive 100% of my refund back and did not have to pay for shipping to and from, so the company does stand behind their product in that sense. I wish it had worked a little bit more magical like other users have reported, but can't say it did much for me, but I'm glad I did give it a shot and try it.

Thank you for taking the time to share this review, Steve.

We appreciate your honesty. Mendi certainly isn't a magical solution, nor do we want to present it as one. Everyone's experience is different, and we believe it's important to approach brain training with realistic expectations.

We're glad you gave Mendi a fair chance, and even though it didn't quite deliver everything you'd hoped for, we're grateful you took the time to explore it and share your experience.

Mendi makes me less reactive

I've been using Mendi on and off for a few years and really love it. I notice that when I'm consistent with my practice - no matter how well it goes - that I feel more "space" internally. So instead of being impatient or reactive to situations at work, with family, or even in a public setting, I am able to take a beat and then respond. That "space" even if it's just a moment, is an incredible gift in my life and has improved my relationships considerably.

Refund? Only if you work very hard

I ordered the product and tried it a few times, trusting in the refund policy. The product did nothing that I could perceive and the app was wonky. So I returned the item at Mendi.io's expense. All good so far. The company received the item, and then radio silence. I emailed over two weeks, and received emails of "we're working on it." Finally contested the charge with my credit card. Be warned, you will have to work very hard if you charge your mind to get a refund.

Hi @AllAmericanDad, we’re sorry this was your experience.

Your order has been refunded in full. The process took a few days longer than expected, and we understand how frustrating that wait can be.

We’re glad we were able to get the matter resolved. Thank you for giving Mendi a try!

It Really Works if You Use it Consecutively

I have been using Mendi now for over two years and I can say that it works. The only thing required from you is the commitment to stick to it long enough to see the results. For me, I noticed subtle changes in my concentration on day 10 then a significant change around day 20 or so. Once you see the results you won't want to stop.

The Mendi is changing my life!

The Mendi is changing my life!! I had never heard of it, I had been thinking about doing in office neuro feedback though but doing one, maybe 2 sessions is about the cost of the Mendi. I saw an ad for the Mendi, watched a couple videos and decided to purchase. I had no idea the impact this one have on me, I feel so much calmer and regulated! I now don't feel over-stimulated and overwhelmed constantly! I've also noticed changes in my kids from doing it as well, better focus, better emotional regulation! We will never not have a Mendi! Highly recommend!!

Love my Mendi

I've been using Mendi for over a year to help me deal with stress. It has helped me a lot with keeping my mind focused. It has also helped my 10 y/o in anxiety reduction.
I can't recommend it enough.

It's daily coming back to my senses

It's daily coming back to my senses. That's how I experience Mendi, in the modern world full of tasks and distractions. How does this feel like? - it's as coming to my center, focused, not jittery, as being empowered.

I’ve been dealing with Long COVID and…

I’ve been dealing with Long COVID and dysautonomia for several years, with symptoms including poor stress tolerance, nighttime adrenaline surges, and difficulty regulating my nervous system. This went on for almost two years getting progressively worse until I was bedridden and couldn’t even tolerate light or sound, I spent the next year in a wheelchair. While I wouldn’t say that the Mendi device was a miracle cure, it has become a meaningful part of my recovery toolkit.

One of the biggest benefits I’ve noticed has been improved emotional regulation and self-awareness. Regular sessions seemed to help me become more resilient to stress and better able to recognize when I was becoming overwhelmed, allowing me to calm myself more effectively. Over time, I felt like I had more control over my emotional responses and less of a tendency to get stuck in a heightened stress state.

Recovery from Long COVID has involved many approaches for me, and I can’t attribute my improvement to any single thing. However, I do believe that Mendi has been a helpful contributor to my overall progress, particularly in supporting nervous system regulation and emotional control.

The app and training process were straightforward to use, and I appreciated having an objective way to practice a skill that otherwise feels very abstract.

I think Mendi is worth considering for people who are interested in neurofeedback, stress management, emotional regulation, or supporting recovery from conditions that affect the nervous system. My experience has been positive, and I’m glad I decided to incorporate it into my routine.

Shipping label issues for return.

The product did not work for me, but that can be an individual response. My friends used similar products that did wonders for them. Did not for me With the 60 day return policy I was confident to give it a shot. It's been 11 days since the day I requested a return. After I figured out how to fill out the PDF return form without printing it, Mendi provided a waybill # to return. This is where the ordeal begun as it did not link to creating a shipping label, just scheduling a pick up. Called DHL if I can drop it off instead. The authorized dealer could not accept with just a waybill number and barcode the only open drop-off on Saturday. Now were in the long weekend, DHL main office is closed Tuesday morning called DHL twice to confirm make sure all goes well when I drop-off the pkg. They assured me I don't have to go to the airport to dropout off. When I arrived at 3:10 pm I was told again that it's not possible to ship like this. (I was getting ready to leave town already late) Called DHL main office at the Airport. DHL team was on it! After 1 hr of being on the phone having to call back as they tried to figure out the issue It turned out nobody at DHL has been able to create a shipping label either. Could not leave town, cancelled the trip.
Contacted Mendi customer service team, but they could only confirm that they have created the links as always. Requested to escalate to someone who can problem solve. No reply. Now I panicked, I imagined I will run out of time, maybe there will be other problems?
Will see if this is a customer service level glitch or ? Will make every effort to contact the CEO.
Update: I could not imagine creating something like this product & not have the seamless follow up for return. After posting here, I did not have to hunt to find the CEO, he reached out to me. He made immediate steps before he contacted me to resolve the situation based on the email I received from customer service. I believe that steps will be taken that this issue will not happen again. I gave this product a 4-star rating. While the product did not produce the personal outcomes I had anticipated, it is supported by excellent leadership that demonstrates a strong belief in the product’s value and maintains the highest standards of integrity.

AMAZING RESULTS!!!

I started using MENDI on November 20.
So far I’ve done 50 sessions. At first, I was doing it in the evening with only one purpose to stop my nervous eye tick (chat GPT told me to try it out before bed time ), for the past month im doing it during the day.
I also added 20mg of CBD with 1 mg THC gummy before bedtime , I also switched to decaf green jasmine tea. Amazing things happened! My eye tick is gone by 90%! I think that by stimulating basal ganglia with MENDI plus CBD is whats stopped sending wrong signals to my brain and as a result the urge to twitch and the squishing my eyes is gone.
It could be a combination of CBD and Nuro feedback. But it’s definitely works! Considering that fact that when it comes to ticks and Tourette’s, there is no cure and nothing can help- I can clearly tell that it helps! I had that tick since I was 10 (I’m 37 now) on and off and the past 3 years has been really hard (I couldn’t stop it, I was feeling the urge to blink my eyes every few seconds, it was exhausting and embarrassing)
I’ve seen drastic results from neuro feedback sessions in the clinic, but it’s way too expensive, so MENDI works just as great. I wasn’t sure that it’s gonna help with motor tick and now I know for a fact- IT WORKS!!!

Product is very flimsy

Product is very flimsy. It never connected via Bluetooth to several devices. It simply will not work. I should have read the reviews before purchase. I have decided to return the device two hours after I received it.

Still stuck with a $30 shipping

I did not notice anything in using this for one month. I didn’t realize I would have to pay shipping return fees for overseas which was $28.65. Just for anyone looking - be aware the shipping fees for a return are FedEx Express and I believe international (?)

Thank you for flagging this for us, Keli.
Returns made within the 60-day return window are completely free, you shouldn’t have to pay a dime for your return. This has been our policy for several years now.

Please email us at support@mendi.io and include a screenshot of the fee or receipt, and we’ll help you resolve this.

We’ll be on the lookout for your email!

Not effective and the the "free returns" is a scam

1. The app is poorly made and also the device it self feels like a 5 dollar product from China.
2. You almost feel stupid as you are sitting there and seeing that the ball moves more by just tilting your head, so if you don't sit perfectly still, there is no way it can work.
3. They clearly state on there website "Free returns" 7 days after receiving it, I want to send it back and they tell me I have to cover shipping costs, which is a scam it self. Fortunately EU-Laws are strict about this...

Update: I did not have to cover the shipping costs, apparently they sent me an outdated return document. Everything still seems a little bit sketchy and unorganized.

Thank you for sharing your experience, Vincent.

We’re sorry that Mendi didn’t meet your expectations and that the return process caused frustration. To clarify for anyone reading: all Mendi returns are free of charge when initiated within the applicable return period, including for EU customers. In this specific case, a prepaid return label was issued, and the return is being handled accordingly.

We also recently extended our full money-back guarantee from 30 to 60 days. This change was made to give users more time to practice consistently, as many people report clearer results after several weeks of regular use.

Regarding effectiveness, Mendi is designed to measure changes in blood flow related to focus and mental effort. Movement can indeed interfere with readings, which is why sessions are intended to be done while sitting still in a low-light environment. That said, we understand that the experience may not resonate with everyone.

We appreciate you giving Mendi a try and for taking the time to leave feedback!

Very disappointing

Very disappointing - the app & game seem like they were built in one week and never improved since then, extremely underwhelming in terms of features, config options, etc - extremely barebone
Item is shipped form overseas which means it'll take a couple of weeks to receive in the US and then customs bill will follow...
