After using the elliptical 2-3x a week for a couple of weeks, it began making clicking noises. The clicking noises became loud rubbing & clanking noises. I was past the 30 day HSN return period, so I called Proform. They would not help unless I purchased their extended warranty. I asked about the 90 warranty that comes with it, and they said that it does not cover service calls look at it..i.e. the 90 day warranty is a joke!" Do yourself a favor and invest your money into something better.
