Tria4x 4.0 model. The one and only FDA approved home laser hair removal system.This item is in excellent working condition no flaws. I have prettysensitive skin so I was never able to use on more then 3 power. After afew uses I did not want to continue treatment. I purchased this in April of 2015 and paid $449.00 for it. It has been stored for acouple years in a drawer, but now looking to find it a new home. I turned it on, tested it on my arm and fully charged it before listing this item. I am proud to say that this come from an ultra clean, smoke free home. Thank you for taking the time to look at my item and happy bidding!
