I'm getting off the Foster Grant Tread Mill. The frames break very predictably within a couple of months of purchase if not sooner. The joke is on their customers. Analysis shows the frames are basically HPS1S-Polycarbonate plastic with a side of Ethylene Glycol Stearate coating. Basically, brittle material that doesn't appear to be designed with the customer in mind at all. Adios FG for me.
