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.

Ordered the item over 4 weeks ago still… Ordered the item over 4 weeks ago still waiting. had a couple of updates from customer service but since the last 2 weeks no one has updated me I am now finding the customer service very poor especially when I took out an insurance for postage which was recommend by the company

45% gels do NOT work at all. Waste of money. Purchased the 45% strength gels, thinking they would definitely work, and they promise to whiten teeth after just 15 minutes, but they have not made my teeth any whiter after several 1 hour sessions. All this gel has done is burnt and irritated my gums and also made my upper lip swell up. Also, the syringes are designed very poorly so that when you take off the cap the hole is too big and too much gel comes out. How hard is it to design decent syringes. Finally, took forever to arrive. Total waste of money, this. Do not buy from them.

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.
