I work out there sometimes and also at MCC, and I know exactly what you're talking about. It was pretty annoying at first. The error messages and stopping for no reason didn't seem right. But they did something a few months ago (I heard it was new software) and the treadmills have been way better. I don't see those errors anymore. Do you? They seem good to me now. I like them. They're much better than the ones at MCC but I guess that's not saying much because the Star Trac ones are high end.
