Bests & Worsts Reviews from Amazon

I used it three times and the belt went out of alignment. I'm only 150 and didn't go above level 4, so it's not like it was hard use. I followed the instructions in the manual and online to adjust, but no luck. It was crooked and continued to remain crooked. I called Pro-form customer service and after waiting on hold for 20 minutes, a nice guy answered the phone. He told me to try tightening it all the way then loosening it the same, then running it to see if it aligned; no luck. He said one of the bolts was probably stripped and they could send me a new one. I asked why a bolt would be stripped on a brand new machine, and he said he didn't know. "You just need to unscrew it and screw in the new one," he instructed. So I asked him to stay on the phone while I did it. Turns out the bolt wouldn't come out of the hole because it was being blocked by the plastic bumper covering it. "It should just fall out when you've unscrewed it all the way," he said. I know how to unscrew a bolt, but continued turning it just in case. "No, it's blocked," I told him. He checked with someone and said "They said it should just fall out." I checked around and there was a screw underneath the plastic part. "Oh, he said, then you probably need to unscrew that." This didn't help my confidence in the company. I tried unscrewing it but it started to strip so I figured I should leave it alone. In light of this, and the fact that I had no faith at this point that the new bolt would actually do the trick, I asked if someone could come fix it. He said they were only allowed to send the bolt. "But I'm within my 90-day parts and LABOR warranty," I told him. He said he'd need to get supervisory approval because it happens a lot and they're "cracking down" on sending people out to do labor. Like I said, nice kid, and I appreciate his candor. But this is not a company I want to do business with. That said, aside from the belt being screwed up, the rest of the treadmill was nice. If you know how to fix things on there when they break and don't anticipate interacting with Pro-form, it might be a good treadmill for you. Personally, this experience made me like Amazon more because it was a no-hassle return. They're sending someone to pick it up.
