I have had a respond laser since 1995. Will not go without one. Always great customer service and a quality product. I swear by them when it comes to abcesses. Have brought several horses back from injury using one over the years. I use it regularly on my horses and have been known to use it on myself. lol
I have a TQ Solo. I use it a lot for soft tissue problems. It’s was $2200 about 5 yrs ago.
Troy Brandenburg has a level 3b hand held for about $300.
I bought one from Troy after my horse had surgery to remove a torn manica flexoria. I’ve been working on her with it daily along with weekly cold water salt therapy and traditional hand walking, wrapping and stall rest for about two months now. We have one more month of rehab before her check up. I don’t know if it is working, but she definitely reacts to it in a positive way (licking, chewing and just relaxing). I figured $300 was a cheap investment and while it’s not as strong as one a professional might have, I can at least do it daily from home.
