Overall would recommend.
Reading the reviews after I bought it, I was concerned I was going to have difficulty getting the extensions in. Upon getting it (and not reading the instructions thoroughly), it seemed as if that was the case. After reading them (granted, not much to read about it), I managed to figure out how to get the pieces in and out of the machine without difficulty. Never had any issues with it over-heating and shutting off, thankfully. I use it at least once every other week to help remove polish on my nails. Overall would recommend.
