Don't know why, perhaps due to rising demand and production bandwidth, but be forewarned quality control is an issue. Assembly is easy enough, though have gap where back separator does not fit snugly after tightening nuts as firm as they will go (see pic). No water level sticker on tank received, so had to measure water manually according to calculations (4 gallons). Siphon was not air tight (even though release valve closed firmly), so had to manually pump instead of siphon. S4 monitor only flashes, not working as of yet and now have to take a apart top of unit to figure out why, currently not resolved after verifying connections and looking at simple solutions on website.
I was introduced to this rower when I joined Orange Theory Fitness four months ago. Since I started using the rower during my OTF sessions I have grown to love the overall workout this thing gives me. In fact, I loved it so much that I purchased the Waterrower Club for my home gym. The overall quality and construction is superb and I'm very satisfied with my purchase. I would highly recommend over any other home gym equipment available. One of the best features is how its so easy to stand up and move out of the way for storage. You can't do that with any treadmill or elliptical. This thing is amazing and worth every penny. Assembly was straightforward and took about 30-45 minutes. Solid, quality construction.
From a fitness perspective, the WaterRower Natural works 84 percent of your muscle mass, helping tone and strengthen your muscles while burning far more calories than most other aerobic machines. The exercise is also low impact, as it removes all the body weight from the ankles, knees, and hips, but still moves the limbs and joints through a full range of motion--from completely extended to completely contracted.
