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.

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.

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.

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 !
