It's easy to use
I've already used this at least six times for my ear (lower and cartilage).  It's easy to use, but if you want to use earrings other than those provided you have to put the back on separately (which is painful).  Also, when I did one at the top of my cartilage, it didn't go all the way through and I had to stab it the rest of the way through - OUCH!  But pretty good for the money - much cheap then getting ears done professionally.
