I used these guys about ten years ago and had great success with hair removal from my lower back. It's still just fine fuzz even ten years later. The hair on the back of my neck and upper back has been much more stubborn and grew back, but less dense. The laser at the time was rather painful and felt like a big rubber band snap each time. They had an icy blower going the whole time to cool the skin quickly, but it still stung. If they went at a higher power, I had some redness and swelling like a sunburn or welts that would clear up within hours. I don't know what kind of laser they used. I've heard some lasers are "Painless" now and I'd be willing to try them. Overall, I was happy with the results at the time and I would do it all again.
They never have that typical, annoying music playing here. If they do play music it is soothing and appropriate for the setting. Just as a side note, I was very impressed with how conveniently located this business was and how close it was to other shopping centers. It was so easy to find, I didn't have any trouble at all. Everyone in my community knows that they are the absolute best in the field.
