Teeth Whitening Gel Refill, 8 Packs, 35% Carbamide Peroxide Whitening Gel for Trays, Profesional Teeth Bleaching Gel for Fast Result, Work with Teeth Whitening Kit, IMOSTY Whitening Gel (8 x 3ml)

This is super easy and fast to use, and I usually keep it on for about an hour. I started seeing a noticable difference after about the third use. There is some sensitivity after using it but nothing like the whitening strips I used to use years ago. I got this type whitening gel as a recommendation from my dentist once I finished invisalign, using my old trays instead of the provided ones, so far it's definitely working and worth it. You get a lot of product for the price.

I prefer this brand over others that I have used. The syringe moves easily, no gushing of solution, not too strong or too weak strength. I can use 1-2 times per eeek without sensitive gums (I drink a lot of black tea).I will continue using this brand.

It doesn’t taste like the name brand does but it whitens just the same. I can’t get a full 30 min treatment bc it thins out fast with my saliva. But my teeth are really white so I’m not complaining.

I have just started using this teeth whitening product. I was worried because some said it burned their gums, but I haven’t had any problems with that. I’ve used it for just over a week and my teeth do seem to be getting whiter. This pkg of teeth whitener will last me quite awhile. I’m still using the first syringe.

I bought an Auraglow blue light whitening system in May which I love and works great. When it was time to order more gel syringes I,unfortunately,picked the cheapest I could find. With the first use I noted the gel had a funkier taste than my Auraglow batch and it also makes me salivate so there is a bit of saliva constantly around my lips trying to exit my mouth for the half hour procedure...a little annoying. As they say...you get what you pay for.

Work as expected. Tube cap can be used to cap tube and keep contents for next use.

Product does not whiten at all! I could tell right away by the consistency it is more fluidly, water like than the original brand Opalescence which is more of a gel consistency. I tried this brand because every once on a while Amazon will pull the 35% Opalescence and it’s not available for some reason, then it’ll magically appear again for purchase. I worked in the dental field for over 10 yrs and majority of dental offices use the Opalescence brand whiteners for patients to purchase, but Amazon sells it at a much cheaper price! I will not be purchasing this product again & you shouldn’t waste your money on it either. I whiten regularly and try to maintain a white smile. I haven’t used any other brand besides Opalescence, which actually works amazing and you can tell the difference immediately. Unlike this brand which I now used three times & it has done absolutely nothing. Once again save your money.

Very good product, worthy for the price, fast delivery.I’ve been using for months and I’ve had got good results.Use it accordingly with the product description and you won’t have any troubles.Mind your gums, the product can burn easily!
