at-Home Teeth Whitening Light Accelerator with Matched Mouth Tray - Grinigh® - Powerful 5 LED Tubes for Teeth Whitening Treatment (Batteries Included)- Blue

It arrived on the dates mentioned. Good value for money. It is a convenient way of removing daily stains from teeth but these are not permanent teeth whitening products.

Works well, i've used this 5 times now and i can see a difference when i use my whitening product. But i don't see as much of a difference as i did with my old one. Also the mouth insert is very large in my opinion, not the most comfortable to keep in your mouth for 15mins. But it does the job and is the cheapest one i could find on here with the mouth insert too.

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.

I wouldn't bother, save your money.

Didn't work at first, after looking further there was a glue like substance on the battery conductor, managed to get it off and now works

Very bright lights and fits price range perfectly.

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.

Didn't help with the whitening process at all. Really hard to breath and keep in your mouth without constantly holding.

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!

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.

I was looking for a silicone teeth whitening tray and wanted to try the light. I do think the light works to help teeth whiten a bit faster- I use it with a painted on gel which I find stays on a bit better than the kinds of whitening gels that you just fill into the tray. This tray is a little loose (like the groove where your teeth go into doesn't hug your teeth well so it wants to move forward and back which can make the gel move around or get out of the tray. Also the light is pretty easy to fit into the tray but wants to pop out pretty easy.

The base where you attach the mouth guard thing was stretchy after one day of use and the light stopped working by the 2nd day. After removing the battery and toggling with it the light turned on and the on off button won't work. The light does the job, don't get me wrong but overall there's better ones. No one wants to deal with this while they have peroxide on their teeth and drooling!

The light was not strong and bright at all, even after switching out the battery. The product itself is very cheaply made.
