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.
The model E’s seat stands 6 inches higher. And while the model D’s monitor rests on an adjustable arm, the E’s sits on unbending metal. These few technical differences do nothing to impact ride feel. We recommend the $200-cheaper model D as the best buy, but the Concept 2 E will appeal to anyone who values a higher seat and more solid construction.
Assembly was challenging. One of the rails could not be attached because the embedded screw in the cross-beam was too crooked to fit into the hole on the rail. I had to place a nut on it to protect the screws and tap until it was true enough cap nut to be attached. The foot board is slightly wider than the top board. I will sand this to match when I reapply the finish. This will need to be done because the wood has a dry, ashy appearance. The wood is beautiful and mostly uniform. This rowing machine is a nice product, but the build quality of the unit I received was disappointing. I felt lucky that the gashes in the carton did not damage the product as the packaging was optimistic. The leading competitor I use at the gym seems to provide slightly more resistance. It is beautiful and useful, but with room for improvement.
Other details include dual rails with four corner wheels that increase seat stability and reduce the amount of sweat buildup; a frame that flips upright for handy storage; and a weight capacity of up to 1,000 pounds. The WaterRower Natural measures 84 by 21 by 22 inches (W x H x D), weighs 117 pounds (with water), and carries a one-year warranty on the frame and components (WaterRower will upgrade the warranty to five years on the frame and three years on the components with the completion of a registration form).
