HEY SEANA! Potential Electrolysis Partner, wassup! 
Well, the only area I ever intended to treat with the one touch is my chin/throat. If I wanted to do my legs as well I would definitely branch out beyond the one touch, but I am honestly really happy with everything and have no regrets. It’s slow to use, but it’s cheap ($300 is still $200 more than $100!), and it’s working.
Tea tree oil really upsets my skin - I usually use aloe if I think of it, but mostly I just wait and it goes away on its own. I am not self conscious about it anyway, although obviously I’d rather not have swelling!
Yeah, I know, I should use a lower setting
I also shouldn’t pick at my scabs (all scabs, not just electrolysis-related), but it’s a powerful force that I cannot resist! I like to “feel” the electricity, I guess, and I’m already waiting 20-30 seconds on level 9. Couldn’t imagine waiting much longer on a lower setting. At any rate, it’s a lot better now on the second round. I am still using level 8-9, but it only takes 10-15 seconds and almost always on the first try.
I found re-inserting the probe more than once into the same follicle caused a lot of damage.
I do have some pigmentation and scarring from the first round which was more damaging (highest setting, long wait times, sometimes 2-3 tries in a follicle), but it’s VERY minor, under my chin, and I can only see it when I’m front of the magnifying mirror with the light on, so it’s really not a big deal to me.
Other thing I noticed was that sometimes the hair would come out but leave the root thingy behind, which would harden in the pore. Often these were easy to squeeze out like a whitehead, but a couple of them caused bumps that I picked at. Not a big deal, but now I am careful to push out any that don’t come out with the hair.
No intention of selling the one-touch. I consider the $100 money well spent!
I maintain that it’s not for everyone, but if you want to spend like $30 you can get a one-touch, some extra probes, and some batteries and you’re good. The only thing is, wipe down the metal thingy on the probe with a damp cloth and then wipe it dry. Leaving salt water on it will cause is to rust.
The only other downside I see to this (which doesn’t apply to me) is that it sucks for fine hair and small pores. The probes are just too thick, I guess.
