I've watched numerous videos online featuring physical therapists Bob and Brad over the years, so when I suffered a fractured tibial plateau, I knew I'd be using their recommendations for rehab when the time came. It was during a PT session at my therapists office that I overheard another client talking about a massage gun he was getting ready to order for his knee injury. He said he'd done extensive research and found one for a good price. I asked him which one he was going to get, and when he said Bob and Brad was the brand, I KNEW it was for me too! I ordered it that day and it has been a life saver for me. Being a 75-yo woman, the 'gun' seemed too heavy for me to manage initially, but once I got used to the weight in my hand, it's been no problem. I use it every day, sometimes twice a day to ease tight tendons and muschle aches. It has options for every ache and pain you can imagine. It charges quickly and holds the charge for a significant period of time. It comes in a great little case to keep all the accessories in one place. Easy to use and easy to carry with me, I love this massage gun. Bob and Brad - they're the most famous physical therapists on the internet and this is only one reason why!UPDATE: Unfortunately for me, the massage gun stopped charging. FORTUNATELY for me, BOB AND BRAD PRODUCTS stand behind their guarantee and within a few days after contacting them, I had a new massage gun in hand. No hassle, plesant experience, and I'm so glad to have relief in hand again!
