Review (3/5): Cheap, but it works. Gloves are awful.
I ordered the three-piece set with lamp, flashlight, and gloves. The gloves are super, god-awful cheap. The material is so thin it is see-through... and if you can see through something -- that means light is passing through it. I wouldn't trust the gloves to protect me at all and you shouldn't either. Thankfully, I already own much better nail lamp gloves and I can just throw these away. The LED lamp and flashlight both work, with the LED lamp powered by USB (it must be plugged in) and the LED flashlight powered by three AAA batteries. The flashlight is super cheap and I don't expect that to last either; it's made of Aluminum -- I think -- and it has these silicone covers on them that slide around and I don't like that as it's annoying when they slide around.
Despite all my complaints -- the lights work. Range of light is 365 to 405 nm, which is near-UV to visible (violet), with near-UV meaning UV wavelengths are near the visible border closer to the violet side. These UV LED lights are cheap, common, and they work, so no complaints there. I'll update this review if this product breaks down, but for now, I give it three stars for "It's OK. It works but the quality is seriously lacking."
