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

I will just say that the light is brilliant but honestly do NOT use that stupid mouth piece it is useless it does not fit around you teeth..... happy with the light but not happy with the mouth piece....

Unsure if this helps brighten my teeth whilst using whitening strips but it's easy to use, function's are simple and feels comfortable in my mouth

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.

As soon as I opened the product, took the plastic strip out of the back. Placed the batteries back in and discovered the blue light come on instantly and I was unable to turn it off. To get the light to go off I had to take the batteries out.

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.

Good fit, my teeth look a little whiter but not sure they would look just as white without using the light?

Very bright lights and fits price range perfectly.
