I have gotten far infrared laser therapy for a year and liked its healing power. But, the salon closed so I had to find an alternative. Hubby found this and I’ve had it awhile now. It heals almost anything to do with soft tissue. Takes more applications but it does work! My daughter strained a very unusual muscle no one ever strains. But, it was extremely painful - enough to call mom. I brought her my Tendlite and it healed her inside of a week. The customer service is great, too!! Have a question? They follow through and quickly!
