J dog
Does not have enough power for thick callouses, but it is twice as powerful as the battery operated unit. My wife needs, the emjoi, to use. I like like to use my dremel, on low, with sandpaper, witch, could tear your skin, or burn you. I don't tear or burn. I wish, they could just make the power adjustable, with the emjoi, for personel comfort. I love useing the emjoi on my hands, they like to get dry, and crack open. The emjoi fixes that issue, and gives me a pedicure on my hands. So it works great for us I would recommend buying one. Also you are not suppost to share the rollers in case of contamination I personally haven't had issues.
