I run 3-5 days per week and 20-25 miles per week on a treadmill. When my Pro-Form died after nearly 10 years, I did some research, asked some friends and purchased a SOLE. For the first maybe 2 years it worked great. We did have somebody come and clean it once a year. Since then I've had parts replaced every year. It's noisy and super loud - and one tech told me it just needed cleaned. Six months later (and even louder) another tech told me he was totally wrong and replaced several parts. I've now owned it about six years and it's out of warranty. I just paid $500 out of pocket for additional service and parts replacement because it was cheaper than a new treadmill. I NEVER had my Pro-Form cleaned or serviced and it lasted me 10 years with no issues and heavy use. When this dies again (it's inevitable) I will purchase another brand. I've even had several techs tell me not to purchase this brand again. I gave it three stars because the functions are easy to use, when it's working it's great, but otherwise will look elsewhere if spending over 2K.
