I’m very happy with my Tendlite, it works great for a home laser therapy machine. I’ve used it on some pulled muscles and it does provide relief. It’s been helpful for scratches and cuts to, they do seem to be healing faster. I know it’s not labeled for animals but I’ve been using it on my old dog a lot. He’s 18 and has bad knees and arthritis. He’s moving around better, sleeping better, and even made it in the couch by himself yesterday!
