The age-defying laser battery has a short expected lifespan. I kept my laser plugged in, but did not use it regularly. I used it off and on over a period of less than three years. During my more recent attempts to use it, I would find that although the device was fully charged, the battery would die in under 4 minutes, not lasting long enough to complete a medium-level treatment.
I eventually called Tria about this and was told by the consultant that the expected lifespan of the battery was just three years. Furthermore, there is no repair service! So there are no replacement batteries or any other support if your device fails after the 1-year warranty! I would have been far better off using the $495 I paid for an IPL treatment. I spent $495 on a device which provided no noticeable results and never will. Its battery, which was not heavily used, is just about dead and cannot be replaced.
Bottom Line: No, I would not recommend this to a friend
