There are times when you call in a repair guy and watch what they do that you say to yourself, "Gee Whiz! I could have done that myself". I promise you, the repair job I had to replace our treadmill walking belt was NOT one of those times. Even the "Do it Yourself" YouTube videos recommended that you let a professional handle this job for our model of Treadmill. The repair guy from Systematic Fitness Solutions did a masterful job of repairing it. He was on time, was friendly, went straight to work, and came equipped to do the job. He added extra touches like lubricating the belts, testing the incline, and checking & tightening nuts/bolts to decrease the loudness of running the treadmill. It looks, sounds, and behaves much like it did when we first got it. We received top notch service and I truly recommend their service.
