I had four lots of laser hair removal on my underarms and on my feet and I found that it works very well on me. All of the hair isn't completely gone, but I would say that it is 80-90% gone. I do have light skin and dark hair though so I am an ideal candidate.
I did have some pain, particularly on my armpits, I'm not sure why, it was just uncomfortable. Not terrible pain, but not pleasant.
Would I recommend it, yes. Do I think it works perfectly, no.
