The robot works nail by nail, and each takes about 30 seconds. You do have to keep your hand still, or else the robot could miss a spot, or end up painting a smidge outside your cuticle. This happened to my thumb (I was admittedly a little shaky from my second cup of coffee). But there was a nail-polish remover pad on hand and I was able to easily get a quick do over. While there’s no fan or drying technology attached to the robot, quick-dry drops were applied straight on top of my completed manicure, which made the red polish firm up so that I could grab my bag and use my phone.
