Query: Omron Missed with This One

Based on so many positive reviews, I thought this is what I need. The first few weeks were great and I especially liked the belt clip that came with - very convenient. But then the aerobic steps measure quit working after three+ weeks and the software became intractible as I attempted to record no aerobic steps. This unit is in the junkyward now.
