Well I learned this, the level of device you get does make a difference
First one was a Remington EP7010, 35 dollars at walmart
I returned that and got a Braun Silk-Epil 9, from Ulta at 140 dollars (same nearly everywhere)
the Braun hurts less, period.... it does hurt on some areas, but nothing like the Remington
Remington I couldnt even get it started on my legs, felt like I was getting zapped by electricity
in a bad way, and it took about 10 passes to clear the spots elsewhere that I tried
The Braun, I did my entire legs and butt in about 15 minutes with only minor discomfort, couple passes was good enough to see huge results.
