Very dissatisfied Very dissatisfied, I ordered the 35%but was burning my gums and leaving them with white marks on. There is no doubt it will whiten your teeth, if you can’t stand the pain and put up with sore gums. I did not overfill the trays, but difficult due to the size of the siringe. I won’t be purchasing this anymore !

Ordering from the uk. Ordering from the uk. Ordered 2 months ago and still haven’t received my order, sent several emails but no response.

The product arrived in damaged package The product arrived in damaged package, after several weeks. The gel smells of pure bleach and it has burnt my gums and inside mouth after 1 use, used minimum amount of gel too as quite cautious. Contacted company on several occasions reporting the problem, with no response… Would definitely not recommend at all.

The delivery time wasn't too bad… The delivery time wasn't too bad considering it comes from America. However, I've been using the system with the gels bought first (didn't know tray wasn't included so ordered tray separately!) For 2 weeks and not seen much difference unfortunately and that's with the 35%. I also keep reading that these led lights are a gimmick and wont actually help teeth whiten. Apparently it's got to be UV lights that work.

Definitely starting to see a difference… Definitely starting to see a difference in the colour of my teeth.. Have spent the last week perfecting how to apply this product so so carefully so not to allow it to come into contact with the gums as it burns so so badly. I have found that using a mouth guard (from a game of speak out) to open the mouth wide and applying the product to each individual tooth with a tiny brush the best way. Usually have to put cotton wool down the sides to avoid saliva running onto teeth. Works best with uv light and also 1 hour rather than 30 mins. I haven't found sensitivity a problem. Hope this review helps someone.
