I hate using this thing. It not only makes a ton of noise, and I have sprayed it liberally in all areas using a quality dry lubricant made specifically for exercise equipment, but the motion is stiff and jerky no matter how much you adjust the knob. It also has a tendency to tip backwards if you happen to not have your feet all the way forward on the treads. I wish I had saved the packaging so I could return it. I also wish I had seen these latest negative reviews before I bought and not only that I paid way more just a few weeks ago than what it costs today. Just a totally disappointing experience no matter how I look at it. Shame on companies like Fitness Quest for putting such garbage out on the market and taking people's hard earned money away from them for nothing in return. I'll be taking this along on my next Goodwill run. If I had to say anything positive about this item it would be that it looks nice and you can use it barefoot.
