Quit functioning after first use.
Used for one session of gel polish removal.  Two weeks later, went to use it and lights indicated operational.  It would run for 3 or 4 seconds, then stop.  I switched bits (why? don't know) but it still would not continue to run.  Return appears to be going smoothly.  It did arrive timely and neatly packaged with clear instructions.  Sad.
