I'm actively working out in a cardiac rehab program twice a week. I'm setting myself up a home gym and wanted a rower to use on the days I don[t go to my program. After checking out several options I ordered this one. It fits my needs nicely--and is functionally as good for my purposes as the commercial units that they use at my rehab program. The assembly of this unit was pretty easy, and if I were nit-picky, I would say that the seat is not as comfortable as found on those big expensive commercial ones--but it's not anything I would object over. I've already recommended this rowing machine to other members of my cardio class.
