Query: Reasonable, however ...

I've been using this machine at my work Gym for the last 2 months on a regular basis. I love the workout programs and the way the machine feels. However just this week I broke the machine!! It turns out that the flywheel attachment bolt has sheared due to metal fatigue. I am not particularly stressing the machine and at 240lbs shouldn't be causing this kind of damage to professional gym equipment (the maximum user weight is 350lbs according to their specs). The machine is used lightly by the staff at my company (maybe 1.5 hours use a day at best). Maybe we had a particularly weak machine or lower quality machine where the welds weren't done properly. Other than this issue, it's a nice machine to use. Very comfortable.Anyway, if you're a professional gym outfit, be wary. Make sure you get a warranty!
