If you're looking at a WaterRower, you're probably also considering the Concept2. They're both great machines, but which you choose depends on your needs. I think the WaterRower is ideal for most people, but not everyone. The WaterRower has a number of advantages vs the Concept 2 - it is quieter, the mechanism up front is lower profile, it has a comfortable seat, it is much better looking, it's easier to stand up when you're not rowing and it's just ... zen-like. There is something about the smoothness of the WaterRower that makes it a joy to use, and because it's quiet you can easily stream your favorite binge-series without cranking the volume too high.
I have also received negative feedback about the resistance. After 15 minutes at the maximum level, you will feel that you are hardly putting an effort to row. However, this won’t be an issue if your weight is less. This could indicate an issue with the oil or gasoline mixture in the piston. Also, issues were mentioned by other customers with the footrests. They’d problem strapping their feet. It is a bigger issue as it becomes difficult for people who have small feet as the feet keeps on slipping. The footrest grip is not tight. This is affecting particularly when you would like to experience a workout without any interruption; when you actually want to go with the flow of workout. Fast rowing also becomes difficult with this type of problem as you have to stop and strap the feet back. However, the problem could be solved by using a wide and thick Velcro straps. Use your creativity and be resourceful while coming up with the ideas to solve the problem of slipping feet.
This type of machine provides a smooth action with little wear and tear to the mechanism, and the flywheel itself could help to keep you cool as you work out. It's worth noting that although water rowers aim for a realistic rowing feel, competitive rowers often use air rowers for land training. They tend to be less expensive than water-powered rowing machines, as well.
As I mentioned, the rowing experience with the WaterRower is amazing. I bought the rower for myself, but my wife was curious and decided to try it out. She loves it, and now rows almost daily. We have a treadmill that neither of us has used since we started rowing - the WaterRower is a much better workout and much more enjoyable at the same time. It's easy to adjust the intensity, pace and duration of your exercise. There is nothing to change on the rower (* see note below), you just row harder or faster, adjust how far you lean forward and back during your stroke. The WaterRower will keep up with you as your fitness increases, all you need to do is keep throwing more and more at it.
