Knall Avis 

It’s a well made unit but not the size I was expecting. The opening is 1200mm. It is to be surface mounted so that the full 1200 opening is available.
The casing is 1200 but the shutter is only 1120. These are the sizes of an internally mounted unit which isn’t what I ordered. It’s really very disappointing.

Been waiting to pay for my order for 2 months. Was told I would be sent a Paypal link after placing my order so I could pay. I have chased them twice and still not been sent anything. If it is this difficult to even pay, imagine if there is a problem with my order!! At least I know now, rather than later.

Excellent quality roller shutter, used on side cupboard as have no shed for storage, website makes it easy to order, German engineering and quality... 5 *

Product arrived very quickly. Fitted in doorway perfectly. Quality of product very suspect. Very delicate and flimsy. Worked fine for a day or so, then things started to go wrong. A few of the laths came away. On inspection I can honestly say that the material used is very thin. I contacted the company and was told that the product was delivered in satisfactory condition so basically tough luck. I then asked for the parts to repair them, but all correspondence ended with them not replying. I then found out that~Knall is just a middle man. They have no service, no parts or no help if product goes wrong. Stay away.

I decided to buy and fit my own roller shutters at my shop. Great price, great product, easy install.

Fast delivery. Great shutters

Terrible service, we have been waiting nearly 3 months for our order. They lied and send it was being delivered, then said its been posted which again it wasnt. We are trying to get a refund but no luck so far.

Good product. Came within the time frame.

Quick delivery

We are very pleased with our exterior, electric roller shutters. They are ideal for added security, insulation and privacy to our summerhouse. The customer service with this company was fabulous. In particular Kamila who made sure we had the correct colours and parts. A big thank you to her and Knall. We will look at this company first in the future, should we need further products.

Easy to use Web site made ordering easy. Even when the delivery van broke down they called and kept me up to date and made sure my delivery got here on the day I was told.
I brought a windows shutter which was well made and really good quality.

Shutter itself is reasonable build quality.
Pre assembled, made to measure, colour, guide fixings, sizes all good.
Only criticism was manual external switch, poor quality, not as described, sent letter explaining the situation and was promised missing fitting backplate/housing. Not what I wanted, paid premium for the switch gear got low quality interior switch. Never even got the promised backplate even after complaining in writing.
Hopefully I don’t have any issues with the shutter or motor as my experience with the switch that cost less than a 1/10th of the total price was very poor. Ended up buying the switch I wanted from a different supplier, but annoyed I paid Knall for it too and got nothing like it.

Reply to Knall, I informed you I wanted the advertised outdoor switch, you confided you advertised the wrong item, you promised the back plate but never sent it. I gave up waiting and purchased a decent quality external waterproof switch that you weren’t prepared to make good on. Hence why I have only given three stars - you could’ve honoured your error but chose not to and didn’t send the missing backplate either. Customer care in my experience was poor - sorry but ball was in your court and you failed to act. I did send you multiple emails requesting suitable remedies - you chose not to act on them.

The website is easy to understand & makes measuring & ordering very simple. Delivery time quite good for a made to order item.

Excellent product top quality silent function very easy to use. Super happy with my new roller shutters. Good customer service

Bought blinds for our Fakro roof windows, the fakro blinds have failed a couple of times with the string breaking. These blinds appear to be sturdier and don’t have the string so will hopefully last longer. Fit on sides is as good if not better than original, fit on bottom does let it a tiny bit of light in. Overall very happy so far

No acknowledgement of order and no response to several e-mails; I presume that this company is no longer in business.

E-mails sent 14th, 18th and 20th July, the first asking if order received and when to pay; no response from company at all.

Blinds promised in 2 weeks
6 weeks later they have still not appeared. Address on Web site is in UK but I seem to be endlessly dealing with someone in Poland not that that would be a problem if they actually delivered on time.

Can't comment on the quality of the product as I have not seen it yet but on the basis of their promised delivery time o ly one star

I placed an order for blinds and paid over £500, on 05.05.2022. Despite shipment notification which I received on 14.06.2022 (a month ago!!!) I still have not received the goods. My e-mail to Knall asking for an update and tracking details remained unanswered. No telephone number on their UK website so decided to call their Polish office. Promised that blinds would be delivered during weekend – did not happen. Further phone calls and still no firm delivery day, no tracking number or anything.

Well over two months after placing an order, I cannot believe it takes more than a month to deliver blinds which have apparently been sent. I’m losing any hope I would receive the goods I've paid for.
