Excellent professional grade products! I have been using these teeth whitening products for about 7 years now. Professional grade, easy to use, and amazing results. I do monthly touch ups to keep my smile bright. The pricing is excellent! I recommend getting the the blue mineralizing gel also and use immediately following each treatment. I do not have any sensitivity when I use the two together.

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.

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.

Item never arrived If I could leave 0 I would, I ordered the item a day after a colleague at work ordered theirs. They received their order over 2 weeks ago, I'm still waiting.....so as I haven't received it I am unable to leave a review of how good it is.
