i had one (you can see a bit on the pic) on the inner upper arm, took nearly 4 hours......**** me that stung a bit..
on the outer arm, no problems..but get inside, a different ball game...
also around the nipple area on my chest...not nice...
The outer arms doesnt hurt much at all. I bet the nipple area nacked!!
Ill be getting quite alot done near my pits when i get my new one. Not looking forward to that!
