I am on my second Proform elliptical of this model. I had my first one for almost 4 years. After 3 years, the axel broke and my husband ordered parts to repair it. However, the wrong parts were sent twice. Finally it was repaired but the parts were still not quite right. The same problem happened again 8 months afterwards- the axel broke again. This time it was not repairable. So we bought a new one at Sears. This time we bought a 3 year extended warranty.
