The Sole F80 has an outstanding reputation. However, it is also notorious for the risk of cutting a wire during assembly. If just one wire was cut on delivery, why not splice it instead of going through the hassle of returning the treadmill? This is one heavy piece of machinery!
I recently planned to buy a Sole F80 but got a great deal on a Spirit XT600, made by the same company.
No cut wires, but a very annoying and worrying squeak. Loosening 5 screws the hood came off the motor/electronics area. The ribbed drive belt was not centered on the ribbed motor pulley. I slid the pulley over 1 rib to center it, and problem gone.
