Query: Great when it works!!

This is a great little stepper until that darn, shabby pulley cable breaks. This is my 6th, machine which just broke, so the 7th will be here tomorrow. I keep returning them as I got the lifetime warranty for $5, so I don't have to pay to get a new one. I go in, get another one, and give them the broken one. They know me in the store now.I use the machine for 35 minutes, 7 days a week.MAKE STRONGER PULLEY CABLES. HELLO!? That's all that breaks on it. You would think they would have gotten the picture by now.
