I keep forgetting to finish using all my strips, so I can't comment on overall effectiveness, but I can report on my experience so far. The strips are easy to apply to your teeth. They are very similar to Crest Whitestrips. I find that it works best to make sure your teeth are really dry before applying. My bottom teeth were a little moist on the first try and the bottom strip didn't stick very well. They're not uncomfortable, nor do they taste bad. For the last 5 minutes you place the light in your mouth and it's not uncomfortable either. They don't leave much residue when you remove the strips either. I used these for 2 days and on the third morning I woke up with some bottom tooth sensitivity to cold air. I decided that I'm primarily interested in whitening my top teeth and they didn't have any sensitivity so I only used the top strips for the third treatment on. The sensitivity wasn't unbearable but I didn't feel it necessary to continue on with the bottom strips.

I feel like it worked for the few times i used it but the second i went to use it after a month or two the light doesn’t turn on at all. even after a max of 5 treatments

the whitening strips themselves are fine but when i tried the blue light it wouldn’t turn on at all.

Thought it was gonna be better I put the stripes on for 30 minutes it burned my gums and then I put the light on for 5 minutes when I took it off the stuff from the stripes stayed on my guns now my guns have this white stuff on it and I can’t get it off

If you have sensitive teeth, which I do, don’t use. Or it could of just been me?! I was not a fan! While using the strips it was fine, when I applied the light, the pain was immense in my front teeth! I had severe sensitivity for days after using!

The box doesn’t have much information on how to use the product or how often and the website just says refer to the box. Also I can’t tell a difference after using it

I don’t have sensitive teeth but after one use my teeth hurt. If you have sensitive teeth stay far away! I did use them a second time and it was worse. I stopped using them. They were easy to use and I did notice a little change in the color after two uses but the sensitivity is too much to continue.

I thought I had seen a noticeable difference in the first couple of times I used it, but upon photo comparison, it really wasn't that great. The strips also slid off often, and the light was cool but didn't seem to make the effect better. I had better results with Crest or even just the generic Target brands.

Caused extreme sensitivity. The company does give you 100% money back guaranteed, so it is worth trying if you don't have sensitivity issues.

I’m on day 3 and noticing a difference, but the strips do not stick to teeth. About half the strip doesn’t stick. Also, the top and bottom strip are the same size?
