I've had acceptable results from an electric trimmer as long as I pull things taut and was careful, I just wanted something a bit less time consuming.
My entire left armpit is currently splotchy pink and painful, as are the nips, so I'm not even going to attempt to put it on my lower bits. I'm more mad that even after all that 3/4 of the hair was still there, so it really didn't do much of anything other than burn me.
There's an electrolysis place nearby that I think i'll look into next payday, i just want it all gone, permanently, starting with the undercarriage and bits, and chest (manboob-stubble HURTS!)
