I've tried a lot of nail lamps, and I have to say this is the most unique design I've ever seen. It does have to be plugged in, but it has a bendable gooseneck design, that allows you to lay it out flat to store it. So basically you get a full size lamp but if you're short on storage space, this could easily lay flat in a very small space.
It seems like such a good value I almost can't believe it. It works really well with three timer settings. Comes with the cord and instructions. The other nice thing about this item is that it comes presented in a very nice giftable way. There's even a little printed tissue paper inside the box.
Very nice lamp very unique and versatile and takes very little room to store.
