Not impressed Quickly received. Seemed pretty simple however there no instructions as to how often you should be using and staying when you’re supposed to use the red light therapy , is it immediately after the blue light therapy or at a later time using more whitening gel. Then there’s that the whitening gel isn’t the easiest to know where you’ve put it and doesn’t really stay on to well as it’s hard to have your teeth completely dry. Truth be told I’ve been using for couple weeks now 1-2 times a week and see no difference.

Great service! Received lip oil & lip scrub, it's amazing! Also pre-ordered the purple whitening toothpaste, website was easy to use! Highly recommend these products

One of the best whitening systems I’ve… One of the best whitening systems I’ve ever used ! The battery runs long, the wireless system is so convenient for on the go and the results are insane. Just after first time, you could see a difference. 10/10 would recommend !

The best 11/10 always!!! I love all of the products - toothbrush, AM/PM toothpaste (it’s the only one that doesn’t make me break out), the whitening kit, lip oil, scrub…it’s all incredible and so is Dave!

Not sure yet I didn't like that there were no directions. Also, I thought I ordered 2 possibly 3 "pens" but what it really was was misinformation and/or misunderstanding. As for how the carbemide peroxide works I have no idea. I'm afraid to use it without directions.
