"My one-touch was only $10 and came with two probes, so I'll just buy another unit." - That was my plan
However I priced out probes and units and found a set of probes cheaper than a new unit. Not by much but I'm on a budget.
So far, still VERY happy with this machine! I definitely feel as though I'm making progress in total quantity of hair left to treat, as well as in speed and efficacy of use of the machine.
I am still getting scabbing because I crept back up to level 9 but it does go away fairly quickly. I find aloe works the best to heal it fast, and/or an ice pack if it looks red. If I'm going somewhere special I'll just use some makeup.
I do have the odd dark spot but honestly it's way better than the hair, and it'll fade in time (I've had dark scars like that that lasted months or years, but they all go away eventually).
The dots on my legs - no idea what the deal is. They are still there. The other day I was scratching my leg with a butter knife (it's mosquito season) and I scraped them off so that's good I guess? They are fading and I think they'll go away but definitely a winter project.
