With the relatively long warranty for a machine in this price range, you might want to take a chance on it but we wouldn't. My brother in law had 5 of these delivered before they could get one to work.
If you are my brother in law, I am no longer in the treadmill repair business but If you are just a walker, this is an option but they had to take so much cost out of it to get it to $799 that we wouldn't expect it to last. Sole's strong suit is in making high quality folding units at a much higher price point than this. They don't have specific expertise in making an $800 treadmill and it shows. In the past, we have expected more from Sole but this is one of those cases where you can't make a quality machine for this price.
