Comments: I bought this is Jan 2011. I use it 2-4 time per week for about 15-20 miles per week. It always feels solid. I run at most 7 mph, I haven't taken it any higher for extended time. It feels better than any treadmill I have used at the gym this year, maybe it's the QuadFlex. I have rheumatoid arthritis so I want to protect my joints while running. I expect to use this forever...love it!
