I’ve owned my 22 year old mare, Lace, since 1997 and have had many problems keeping her sound due to a pre-existing injury. After many years of trying everything on the market I decided to hire the Photizo unit. It really is a miracle machine. After only a weeks use the trauma tissue has virtually gone. I also use it myself as I have osteoarthritis and we are both now out and about winning shows, pain free and very happy.
