I don't know how this machine compares to others. I have no idea. Here's what I know: I've had treadmills and elliptical machines, weight benches and several exercise appliances from infomercials. They all work exactly like they should if you use the equipment on a consistent basis. That's where the problem comes in. I would always give up eventually and the machine would sit in the corner, covered with my laundry, laughing at me. I bought this rower without ever even trying one at the gym because I was desperate to do something (and I voted for Frank Underwood). This was the one machine I was not only able to stick with, but I now eagerly look forward to using. It started a chain reaction that changed everything. You know those incredible before/after transformation pictures you see on weight loss shows? I'm one of those guys now. Rowing is like a 'secret' in the fitness world in the way there is so little emphasis. However, in terms of results, it is so much more efficient. It works your upper and lower body at the same time, huge cardio/fat burner and builds muscle like crazy. I'm glad I'm in on the secret too.
For a third option, you can look to hydraulic machines, which use pistons to generate resistance. Hydraulic rowers are quiet, and they also tend to be smaller and cheaper than other kinds of rowing machines, but you won’t get the same smooth rowing feel, or the consistency of resistance, that you would get with an air or water rower. What's more, reviewer after reviewer has found them unreliable and high-maintenance.
The most commonly damaged piece of rowing equipment is the skeg, which is a metal or plastic fin that comes out of the bottom of the boat to help maintain stability, and to assist in steering. Since the skeg sticks out below the hull of the boat it is the most vulnerable to damage, however it is relatively easy to replace skegs by gluing a new one on. Hull damage is also a significant concern both for maintaining equipment, and for rower safety. Hull damage can be caused by submerged logs, poor strapping to trailers, and collisions with other boats, docks, rocks, etc.
Outside of resistance type, we found the number-one arbiter of ride feel to be cord quality. Water ergometers tend to employ nylon cords, while air ergometers feature metal chains — a durability factor we anticipated would result in our favoring air. But while all three water rowers aced our expectation of smooth, high-tension strokes, perfecting the chain seems to be more difficult: Some tug with just a slight rumble, others feature bouncy, grinding chains that are incredibly loud, something akin to angry snoring. As for nylon, the best wind and unwind like elastic silk — no slack, no sound, no catching, just perfectly even tension throughout the stroke.
