Direct 2u Wholesale Comfort Fit Teeth Whitening Trays, 8 Count

Were melted blobs when I received them.

VERY loose fit....I bought these to use with the blue stuff for sensitivity and I do as well just rubbing the stuff on my teeth with my finger. I have custom trays from my dentist and buy bleach from Amazon. These would work to whiten teeth some, but I would get bleach on my gums and the bleach would be diluted with salvia, so not as effective. Don't put in boiling water...boil water and let it cool for 5 minutes.

These are difficult to work with, very easy to mess up, and thin. However those properties also make them the only trays that have ever given me a true custom fit for whitening. It takes a lot of patience and trial and error, but if you want to avoid going to the dentist for custom trays, this is about as close as I've been able to get.

The trays worked as well as they're supposed to, the only fault with bought trays is they really can't fit all that well over your teeth, so the product I'd say gets watered down so to speak during the night. I'd probably still recommend getting proper trays fitted at the dentist

I bought this as replacement for another set of trays. I purchased the 4 pack of trays and only needed one to make the proper set, so they are fairly easy to use. If you are considering this as a purchase they work great as replacements from the dentist and will prevent the gel from getting on your gums. A few recommendations are, take your time molding the set as they will adhere to themselves and dip them for 2 seconds and mold and repeat, you will not get the perfect mold on the first try. Also for bleaching teeth in general , if you have gel that gets on your gums, remove it with a q tip immediately to prevent irritation. The other thing I do if gel leakage is a problem from drooling that day is apply gel with a cotton-less q tip, then place they trays on and finally take another q tip and run a VERY small amount of petroleum jelly on the exposed gum area (excess gel will not penetrate as much to the gums and prevents sore gums). As Always if you have severe pain and discomfort, cease use and seek the help of your dentist.

Bought an easier one

They stretch out very easy, although theye mold to your teeth when you mold, they ultimately are not the greatest.

This product is great and works really well providing that you pay close attention to the process. timing of heating the material is critical as it can quickly destroy the product. The tendency is to let it go too long and have the water be too hot.
