Review on Gelish Harmony Pro: The Ultimate 18W LED Gel Nail Soak Off Polish Curing Light Lamp by John Caine

Works worldwide No transformer required. You only need a plug converter. The US version comes with two flat pins and a sticker on the plug that says "Input 100-240V, 50/60Hz, 0.5A". Fits sideways into my converter (which costs less than £2). Works perfectly. I cover it with a kitchen towel to protect my eyes from the light. I like it when the power button lights up. I don't want a sensor. But I keep touching the inside with wet nails! They're not even long! I'll get used to it, I'm sure. Upgraded 18G may be better for customer use. I'm not sure, but Revain may not be covered by the manufacturer's warranty and possibly professional liability insurance. I bought from Cosmetics Central and would highly recommend them for international shipping.
