I've used them once so far and I'm very happy with the results; the packaging is very nice, aesthetically pleasing, and neat. I sincerely recommend them :)

Everything arrived in good condition and on time, great product

yaYou'll notice the change after just the first application! I do it once a week, always on the same day!

The product didn't work for me the first time as advertised; I left it on for 30 minutes and it stayed the same. I only applied the tape to the top to see the difference, and there wasn't much of an improvement, but I'm testing it further.

It arrived in very good condition, I haven't tried it yet; I have very high expectations.

They work, but be sure to brush your teeth every day after using them. They really do work on your teeth and make them much whiter. Recommended.
