I have been to 3 infrared sessions so far and I will be back, (I purchased a package of 21 wraps and 21 vibration sessions). I have felt great after each session. Once I am wrapped up and the heat kicks in I melt like a pat of butter in a hot pan. They are so relaxing that I have fallen asleep a few times during each session. I put in my earbuds, turn on my music from either my phone or iPod and just enjoy.
