We purchased the AFG 4.1 AE elliptical because of its perfect configuration and all its bells and whistles. But as soon as we started using it, bearings noises and cracking noises started to dull our experience. The dealer replaced the unit immediately and the brand new one was even worse! Then they changed the flywheel twice, and got still worst. They finally reimbursed us and we are now contemplating a Sole E95.
