Review (5/5): It's the same one in China.
It looked exactly like the one used by my nail lady in China, a humble box with a black switch and little red timer button on top right corner, and a sliding plate for your hand. Hell, even the blue covering foil on the sliding plate looked exactly the same....
Needless to say, I'm happy, and surprised. The lady used this one for years, so I'm looking forward to stick with this one.
