First time I went it was great and pain free. Second time I went they said their normal machine was broken and used an older version on me. This one hurt pretty bad but it was tolerable. Afterwards my armpits felt like they were on fire I went and got aloe Vera to put on them. I had dark spots on my underarms that stayed for three weeks. I called and complained and the manager told me that "she used the same machine on herself"... Like that matters to me or my dark marks on my arms. Never going back.
