Grinigh 5 Led Teeth Whitening Accelerator Light With Matched Mouth Tray | Batteries Included | Blue

I used this with some whitening strips. At first I was skeptical that the LED would make a difference but it does make the whitening strips more effective. I have used it for 3 half hour long whitening treatments so far and I found it works well and is reasonably comfortable to wear for that time. My teeth do look a lot better. I find it works better with the whitening strips than gel because the gel doesn't stay on your teeth and goes everywhere. I think this works well for that.

Bought this to use with a tooth whitening gel bought separately. This little gadget is easy to use: just a simple on/off switch to operate. Comes with batteries which are pre-installed with a plastic insulating disc to prevent premature discharge during storage/transit. Simply remove this on receipt and you are ready to go. Battery compartment comprises a simple twist to lock/unlock cover. The included mouth tray is specially designed to clip onto the curved LED window and is ultra clear to allow full diffusion of the blue LED light onto the teeth - even those at the sides of the mouth. It is very soft and pliable and is very comfortable during use. Once you have finished your whitening treatment, you simply detach the mouth tray from the light unit for cleaning. Very good product at a bargain price.

Works great! I used my whitener without the light and barely saw any change then I used the light and saw a five shade difference!

This product does what it says on the tin. Negative reviewers just aren’t following instructions. It works fine. When you receive it you have to take out the batteries, take off the plastic seal in between them and then put them back in upside down. They’re transported the wrong way to save the battery.

It fits in your mouth really well and don't move as much
