Query: Horrible purchase

After a week or so of use, treadmill is pretty much dead in the water. Programming is awkward to begin with, but for some reason I can't even get the thing to start up properly now...I'll begin to program in a workout regimen and the damn thing shifts back to the start screen after mashing a couple of buttons. Or, even worse, I'll get the thing programmed and the treadmill simply stops after getting maybe 30 seconds into my routine. Customer service at Horizon is a joke. They've mailed me some part that hopefully will cure this hunk of junk, yet I'm still trying to figure out how (and when) they'll get a technician out here to actually complete warranty repairs. I highly recommend against purchasing this item.
