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 !

The Seattle has is over If you’re tired of searching for a whitening product only to be left disappointed at the poor results, then then look no further. This product will be the last whitening product you ever need to buy. It has a noticeable effect after just one use, and becomes more and more effective with every use thereafter. Fairly priced, arrives quickly and produces impressive results. I won’t buy whitening products from anyone else now.

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.

Order has not arrived Ordered in the middle of May and it still hasn’t arrived. I have emailed to asks or information but have received no reply. Was warned deliveries might be late because of the virus but this is worrying.
