I finally, after several days (ok, several weeks - I have been gardening) of not getting on this treadmill, decided to do a quick 10 min. or so and it's finally decided it's worn out - the belt is slipping and rubbing on one side on the back roller and it has several other "issues" too. It's a second-hand one - already been through two other owners, who took exercise very seriously! I think I deserve a new one - looked online a few places, and they're not that expensive, when you consider the value to your well-being. I really prefer this to walking outdoors, and I don't need a top-of-the-line one, not going to be jogging on it - and I WILL use it - kinda bummed today, when I was all motivated, but sorta excited also that I decided I deserved a new one. Anyone else use one?
