Row machine looks like it's a $600 unit. If you're in the market for a water rower I'd spend the money on the real Water Rower. I was wanting the Water Rower but after this poor experience I just want something that lasts and is warranted the longest. I purchased a concept2 that had arrived and is a much better quality unit. The computer is much better.
The rowing machine itself is unlike any other on the market with its patented water filled flywheel. It is hard to exactly copy the action of a scull on the water, but the mechanics of the flywheel spinning in water comes in a close second on dry land. The fact that the water is 800 times denser than air means that there is no need for any extra resistance or dampening that you will find in normal air rowers. The faster you pull, the more resistance is generated giving it infinite variability. However, if you want to be able to practice rowing with a faster stroke, you will have to reduce the amount of water in the tank unlike an air rower where you just have to adjust the baffle.
