Review (1/5): A great concept with a horrible execution
As you can see from the photo, I've got a fully charged and functional remote here with either no power going to the mouthpiece, or a series of defective lights in the mouthpiece. This one is going back and I'm not bothering to have it replaced by Amazon. I'll find another product that is better made in this price point or take my refund and go get a drugstore strip kit and deal with that mess. Obviously I can't say whether or not it whitens, or whether it's easy to use. The overall design is nice, but I have no clue whether the mouthpiece is even comfortable. The whitening gel doesn't taste bad (I got that far before finding out I'd been sold a dud), and the included lip treatment is a nice addition as it does help protect from the peroxide. Unfortunately, the manufacturing standards for this kit are shockingly low for the price charged. It all feels a bit too cheap to risk trying a replacement.
