Venus White Ultra Whitening Trays

I used this product every night for 1 week as i was directed by my dentist. I normally do not have sensitive teeth but this product had my mouth aching' for a while. My teeth got about 1-2 shades lighter after the 1 week. Would not recommend for those with already sensitive teeth.

These are a cheap alternative to other custom trays. Keep in mind they won't affect your back teeth. Shouldn't be a problem unless you have an awfully wide smile. Originally purchased these from my dentist, then followed up with Amazon. Expect some sensitivity but your mileage may vary.

The trays are pretty flimsy and hard to keep them in place but what do you expect for 30 bucks? Anyways my teeth looked noticeably whiter for about a week and then they turned back to how they were before. I wouldn't buy them again. And I got these based off a recommendation from my dentist... I'd rather spend more money on a treatment that will last.

This product is very effective at whitening teeth, as claimed. It does, however, take a little practice using it correctly. The whitening gel is contained in plastic trays that are really flimsy. You have to quickly put these in place and bite down to secure the trays. The more gel you have in contact with your teeth, the better it will work. I put these in and then watch a movie. You quickly forget they're there. You do have to continue to bite down or the trays will just fall out. I keep it in place for about 2 hours per usage instead of the 30 to 45 minutes recommended and have not experienced any problems. The gel will irritate your gums so take care not to let it ooze out of the trays.It really is amazing how noticeably and significantly whiter your teeth become after just one usage. It does seem the trays don't continue to whiten your teeth. After about the third or fourth application your teeth are as white as they're going to get with this product.Overall, I'm very pleased. Pleased enough not to want any other whitening products, whether used at home or at the dentist. Looking at it from that perspective, this product is a real bargain.

Stick with Crest whitening strips as these do NOT do the job at all! I bought these for me and my mom and there was zero difference after following the directions exactly and using for one week. I am so disappointed in this purchase! Manufacturer will not take any blame for these not working. They do not back their product.

Good product for the price! First te I used it I purchased it from my dentist office for a lot more money.It did not make my teeth feel sensitive. The trays stay in place as long as you don't move your mouth!

The product seemed stale and dry..Please look into the problem, is it on the shelf too lonh? Would like to know what other similar product is recommended?

Product works well, I only used it 4 days and noticed an improvement. Does leave your teeth sensitive, but it goes away after a few days. I would use again.
