I was a little apprehensive, but I used it on a patient and it really worked! Healing has improved a lot, I even tested it on a piercing of mine to help heal. Worth the investment for the value. Came without any problem and everything working perfectly

I think it was better buy for the office, it works very well, I'm using a lot and results are very good. Lack to know durability.

Perfect

T right, I still haven't measured the light to know if it's on the correct wavelength, but it looks good yes
