ReNu Avis 

I ordered the dog brush, which was fine, but they started charging me $43.48 every 2 weeks for a VIP membership. I never signed up for that. My account showed no active subscriptions. I did not receive any emails regarding a membership (although I did receive many, many other emails).

This company was prompt, simple, efficient and easy to use once i received the product! I was well pleased the moment I used the product!

Update 9/13/26: The company claims that they will reverse the charges, but no surprise, haven’t heard from them in regards to that. They called me last week to give them a review?! Most random thing ever. Also, I went to charge my brush today with the charging cord they sent with their brush. ITS NOT EVEN THE CORRECT CHARGING CORD FOR THE PRODUCT!! The brush requires a USB C, they sent a MICRO USB. I stand by my rating, and would rate ZERO if it was possible.

CRAP PRODUCT and charged three times! Buyer beware. The brush is cheaply made. The mister does not work. I bought the “Starter Grooming Kit” for $39.99 + tax for a total of $43.23 on 8/15/26. On 8/18/26 my order was processed and then 10 days later the product arrived on 8/28/26. I was charged on 8/20/26 for $39.99 and then again on 8/27/26 for $39.99. Three charges all before I even had received their crappy product. I emailed them asking why I had been charged three times and said they needed to refund me immediately. They responded back apologizing and saying they would reverse the charges. They NEVER did. I didn’t sign up for any sort of subscription and even if I had unintentionally, why would I be charged 39.99 seven days apart? I then contacted my bank who is now dealing with it on my behalf.

Did not mist. Contacted customer service and contact person said that they would send another device. Have not received.

Recently checked my bank account and was charged 3 times for what I received. Emailed Renu, no response.

Did not received replacement and was charged 3 times. Do not buy

I was able to remove so much fur. Really
Helps get at the undercoat.

A lot of hair comes off, and my dog loves it more hair comes off with this product than any other brush I don't and I've owned several

Our dog liked being brushed, her fur felt softer and smelled the good.

I have been writing emails back and forth with this company’s joke of a ”customer service team” Since July 17, 2026. They have answered a couple emails saying they will escalate this or get a replacement or issue a refund. They have done NOTHING but ghost me. That is bad business and I will leave a review once a week to bring down your star rating until you refund me. GIVE ME MY MONEY BACK! For a company supposedly located in Denver, Co…you run this business like you’re based in China and you don’t care about your appearance to the public or any customer service. You should be embarrassed.

I am currently on the phone with their customer service team and will be recording exactly what happens for an up to date outcome…
Of course they act like they have never even heard of me or a problem with my order. Despite the fact that I have tons of emails proving the opposite. 1st they offered me a 30% partial refund and to keep the product. THE BROKEN PRODUCT THAT CANNOT BE USED! Then she offered a 60% refund. Now I’m letting her know she can put me on the phone with someone over her who can actually help me bc I won’t accept anything other than a full refund. And now I’m on hold again. 21min of wasted time arguing about an unusable product that they don’t want to refund my money for. 26min later and they finally want to give me a full refund bc I said I was recording this and will be including the interaction with my next review. I sure hope I see that refund in the next 3-5 business days as promised or I will be leaving another review. SHAMEFUL CUSTOMER SERVICE!!! DO BETTER!!

Works better on shorter coats than my long haired dogs mats but pretty good over all

Finn is my Australian Shephard, and he has a massive thick coat. Keeping him brushed and cleaned of burrs is almost impossible. He HATES being brushed.

The first time I set up this brush and forced him to sit so I could brush him; he showed his displeasure by curling his lips and showing teeth. That is his way of showing me he does not like something.

I started brushing his chest. This is one of his worst spots to get burrs. After a few moments of lip curling, the teeth started to disappear. After 5 minutes of brushing, he laid down on his side and actually sighed! I told him to roll over so I could get his other side, but instead he showed me his belly! (grin) Not long after brushing his belly he actually rolled himself over so I could brush the other side! On his own! I was shocked!

The first brushing removed so much loose hair that I filled up a small trash can to the top and tightly packed with hair. He looked like he had lost weight. He hips and butt is the worst as the hair is the longest and thickest there. I remove massive amounts of hair from that area alone! It was amazing.

So far, it has taken me several days of brushing to get him pretty much cleared of loose hair, burrs and matts, but he comes over and sits for me to brush him with no lip curling in sight!

His coat is now shinny and clean feeling without a bath. He does not scratch like he did before all of this and best of all? No more Finn colored "Tribbles" (Star Trek reference - :) all over the house!

Had an issue with the brush not charging the first time but I got a replacement really quickly without any questions and the new one works as advertised

The thing pulls a lot more undercoat than any slicker brush I've owned before the house is much less furry

Honestly, the long unanticipated delay in delivery of the product was really frustrating and I considered seeking cancelling my order, however when the product ordered in July 9th finally arrived on August 31st I was partially relieved. My angst subsided in discovering that the brush and solution were easy to apply and that my skittish dog Lunaa seemed to enjoy the gentle misting action and brushing effect enough to lay on her back to allow me to brush her chest and stomach areas. Touche! Kudos to the designers of this product and applicator. I'm impressed 👍🏿😁. J Palmer

My order arrived quickly, well packed with no leaky bottles or other damag. I look forward to using it. Thank you!

Agree with another user. Brush didn't produce mist, was just a brush effectively. Didn't sign up to a subscription but still got charged. They said cancelled and would refund but never appeared despite them saying it had been processed that day. Strangely it had been processed that day 3 times over a month! AI response very time. I would not be surprised if they keep trying to take money...complete scam company dont buy!
After posting the review they have replied that they have refunded the money but I would be very surprised if this ever appears as that is what they always say. I will update...

For the first time it wasn't a struggle trying to groom Duke. He LOVED IT and now when he sees me grab ReNu, he comes and lies down so he can get pampered!

The product works just as advertised. I didn’t realize that it would take one bottle of solution per treatment. This the reason for 4 stars rather than 5.

This company is running a huge scam. They will fraudulently sign you up for a recurring subscription that you never agreed to and charge your credit card over and over again. Do not buy from them!

I made a one-time purchase from ReNu and did not knowingly or intentionally enroll in a recurring subscription or authorize ongoing charges to my payment method. After my initial purchase, I was charged three separate times for a recurring subscription that I had not agreed to. I contacted ReNu by email after discovering the recurring charges and specifically requested that they stop charging me and refund the subscription charges. ReNu responded and stated that they would issue a refund and pass along my information/request. Despite this, I have not received the refund that ReNu previously indicated would be issued. Oh, and the dog brush sucks too.

For anyone needing to file a complaint with the FTC, Better Business Bureau, etc., ReNu’s company phone number is 747-338-1517 and their physical address is 3400 Cottage Way, Ste G2 #22576, Sacramento, CA 95825.

The lavenderish scent is light and not super overpowering doesnt smell chemically either

Does the job for light shedding but for heavier coat seasons I still need a full bath so not a complete replacement which I was hoping it would be.
