I’m only giving 4 instead of 5 stars just because I don’t have any reference, since I’m new to doing my own nails. I’m so glad that this was an option since it’s so much more affordable than buying a full size lamp, and I can also do one nail at a time while I’m practicing. Even when I eventually upgrade to a full size lamp, this will still be useful to have for flash curing etc. So I’m very happy!
