Bests & Worsts Reviews from Amazon

I was impressed by all the reviews that said that how quiet the machine was when I bought it. Assembly was not so bad (2.5 hours). Then the squeeking started. Just about after 100 calories burned, there would be a two distinct squeeks at a specific position of the flywheel. We called technical service and the service person called back on the 5th day (he needed to respond before 5 days) and scheduled a visit for a day 10 days AFTER that. The technician inspected the machine and said that such sound was normal, and adjusted the tension on some screws and left. Now the squeeking is starts right after beginning the workout. It is LOUD. As in, you need earplugs, loud. Another call to tech support...
