Pro Teeth Whitening Trays- 4 Pack - No BPA - Safe Clear Color - No Color Additive - Precision Fit Material- Fit Any Mouth Size - Custom Fit - Free carrying case included

Very happy with this whitening kit! The trays are soft and flexible and would fit a wide variety of mouths. The gel is nice and thick, stays on your teeth for as long as you want. It is a very strong mix and works fast, I noticed a big difference the first time I used it, 30 minutes while watching TV. My girlfriend was amazed at how much whiter my smile was. I'm ordering another kit for her. The kit has 2 sets of the trays so 2 people can share one kit, my daughter ran off with the spare trays and half the gel syringes to use at her place. LOL! My dentist charges $70 for a 30 minute session and said it would take 4-5 sessions to get the results I wanted. I paid around $28 for the kit, so at a bare minimum I saved $200-$300.

Works as intended if you follow the instructions provided which are pretty good. Quality product.

I have small teeth. It is easy to go through the steps to mold it and functions good for gels. But the material is thick and there is too bulky. It is hard for me to fully keep mouth shut with upper piece in and impossible with both pieces in.

I purchased these trays for home teeth whitening. The upper tray molded well and I am happy with the top tray. The package comes with 4 trays. I used up three trays trying to get my lower teeth molded, wouldn't work. so I have an upper tray that works well and 3 useless bottom trays. I followed the instructions, but was not able to "suck" all the air out of the bottom tray effectively, therefore the trays for the bottom did not mold well and will not stay in place. Very good for the upper teeth, but not for my lower.

Awful. These things are so thick it’s not even funny. Followed the directions and they did mold to my teeth appropriately, however, there is just so much material that you can’t even close your mouth. Takes up so much room in your mouth that they make you gag. They aren't easy to try to cut down either. The universal guards are enormous too. Don’t waste your money. Very disappointing.

I followed the instructions extremely closely, and they were pretty detailed. It worked just as it said. I bought these for whitening trays. I do have to whiten the top and bottom separately as the trays don't fit well in my mouth together. One tray fits great though and if I needed it for sleeping to avoid grinding as well, I am confident it would be comfortable and work for that as well. It comes with a nice case for the trays and two sets of trays as well which could be useful if you ruin one or need another for someone else.

Molded easy enough and got a good fit, but these are SO incredibly thick. Probably good for a mouth guard, not very comfortable for teeth whitening.

Due to grinding my teeth at night I’ve tried a number of different mouth guards over the years and this is hands down the best. I bought this mainly to use to whiten my teeth as I recently spent the $100 for a night guard from my dentist but wish I had found this first. I found the molding process easy when following the exact instructions included in the package. Not only do the trays fit snuggly, they provide ample material between my teeth so that I’m not able to grind during my sleep. Most importantly they’re extremely comfortable to wear all night.
