I've tried the emjoi, braun, and panasonic and they all work equally as well. I don't think you ever really get used to the pain though, either you can tolerate it or you can't, I'm thankful to be able to. And yes, I do get periodic ingrown hairs and they seem to be the same hair every time. So I guess that's just how I'm made. My most sensitive areas are my knees and my hiney. I find that if you start in a small circle and work outward gradually it hurts less ovverall.
For the life of me I can't understand why these things have two speed settings, does anyone ever use the slower setting?
