Do you need a machine that folds up? If you've decided to avoid a water rower for space reasons, you may prefer a model that folds up for storage. Even better, some rowing machines have wheels fitted to them, so that once it's folded up, you can steer it to a storage space out of the way. You can find a foldable design in many magnetic and some air rowers.
The Water Rower comes partly preassembled in two large boxes. The assembly instructions are reasonably good, and as long as you take your time and follow them carefully (read all the text) it takes about 45 minutes from opening the first box to trying it out. I bought bottles of distilled water to fill it, which made it easy to fill using the included funnel & hose.
Using the same principles that govern the dynamics of a boat in water, the WaterRower S1 Stainless Steel Rower with S4 Monitor provides an unlimited range of resistance making it suitable for a variety of strength and skill levels. In a boat, the faster you move, the greater the drag and the greater the intensity of exercise required to maintain your speed. The limit to the speed you can maintain is you, your physiology, not the machine. For maximum realism and comfort, the WaterRower S1 Stainless Steel Rower's precision spragg clutch engages the instant the handle is pulled, so there is no jerkiness or jarring at the beginning of the stroke. The WaterRower S1 Stainless Steel Rower with S4 Monitor leaves you with the distinct sense that you are gliding effortlessly across the water.

The resistance of your rowing machine impacts how it moves. Select from hydraulic and magnetic rowing resistance. Hydraulic rowers are typically more compact in size, while magnetic machines make little noise as they operate. Details like easy-to-reach tension knobs or buttons allow you to increase or decrease the intensity of your resistance as you train.
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.
