dental Supply Co, USA Teeth Whitening Accelerator Light

Love this, you can also purchase batteries for this at the dollar store which is what I love! Definitely works, great buy!!

Product is not eligible for return and does not work at all. Arrived in damaged packaging with no instructions.

Yeah comes in sketchy ziplock baggyc..didnt even think about this at first, but some other review said "at best its prob been on chinese factory floor" hmm i took a look at it and the plastic IS all scratched up like some recycled cheap plastic ---- so ya might want to put it in some peroxide and clean it first but hey its only $4...uh....if anything you could use this thing as a little flash light its so bright (but its blue)..Also who knows if it really is same level of dentist UV ?

Have wanted to try this for a while and for the price I couldn't pass it up. I was using a whitener tray without the light and could actually see a difference when I used it the first time. It shipped straight from China but works as expected.

It falls apart every time I try to use it.

Love the product however it seems to go bad after a few months of use. Ive changed batteries and the light seems to still be very dim. Perhaps from water getting into it but other then that, great transaction, great product and great service.

I bought two of these and both of them have dead batteries inside. If the seller advertised that batteries wouId need to be purchased separately, I would not have been so frustrated…I would’ve been prepared. They’re not standard batteries people would normally have in their homes, so now a trip to the store is in order. Who knows if the darn things even work. Disappointed.

Great value. It works as described. I've only used it for a few weeks and it got the job done.
