First time trying this procedure and Sun was very informative and reassuring as I was concerned about pain and after effects. There was no pain and the heat was bearable. Ambiance was great. It was just one session so not expecting miracles but will watch to see any differences in mid-section. I plan to go back as I understand will need a few sessions for a problematic area. For sound sensitive people I suggest bringing ear plugs for the vibration sound but Sun did warn me ahead of time. Thanks Sun!
