If you are anything like me, you read the negative reviews to see what some of the complaints could potentially be...I have found none that match with my machine or experience so far. The boxes it came in were a little bunged-up but everything on the inside was perfect. Only took about 15-20 minutes to build (first time building a row machine) and another 5-10 to fill with water. We used it for a little while before we added the danish oil.
I teach pilates and also have several pieces of cardio equipment for my clients to warm up on. I bought a Hi, Rise Club Water Rower model a few years ago . as it turns out, my hard core bikers and elliptical walkers really did not use the Rower. SO it is in great shape. A beautiful piece.  I could not get a good photo in my house as there was not enough light, but if you Google this, you can see just what it looks like. 
In addition to its natural, fluid resistance, the Elite Wave Water Rowing Machine features many performance upgrades that push you to row harder, faster and longer. When mounting the rower, you will immediately notice the ease and customization of the footplates and straps. The footplates, which accommodate a wide range of foot sizes with their adjustable length, feature a heel strap that secures the feet while also allowing the heel to rise higher for a wider range of motion. There are also quick-adjust straps with finger loops so you can quickly secure your feet – even in the middle of the workout. Once you push, extend and bend, the seat glides atop the aluminum rowing beam, providing a smoother workout.
Fitness experts as well as health professionals agree that rowing machines provide one of the best workouts possible. Exercising on a rower will allow you to target the great majority of your muscle groups and give them as hard and challenging a workout as you feel like giving them. On the better rowing machine models, you’ll be able to track your progress and see how your splits are improving.
The WaterRower Club is hand crafted in solid Ash and stained for color. The WaterRower Club has been designed for High Traffic Areas such as Commercial Gyms, Studios, Rehabilitation Clinics, etc. Its Black Rails have been styled to prevent scuffing, other wooden components are finished in an attractive rosewood which are more resistant to soiling than the Natural model. Each machine has been hand finished with Danish Oil and Urethane for protection. Wood has been chosen due to its marvellous engineering properties, primary amongst these is its ability to absorb sound and vibration enhancing the WaterRower's quietness and smoothness of use. Ash, like all woods used in WaterRower construction, is a premium hardwood with incredible longevity and dimensional stability. s For reasons of ecology, all our woods are harvested from replenishable forests.
The water flywheel is comprised of two paddles encased in an enclosed tank of water. As you pull the cable, the paddles move through the water creating resistance. The beauty of this machine is it uses the mass/density of water. The paddles create the drag, so the harder you pull, the more resistance increases. Think about moving your hands through water. The faster you go, the more dense water feels. The slower you go, the less you feel the resistance. And this type of resistance is excellent for your joints. Click here to read the full review.

The frame is beyond durable and is designed for absorbing sound and vibration. There’s no creaking or other sounds that you might expect from wood components. It has a low center of gravity that keeps the rower in place while exerting full rowing power. The polycarbonate water tank is equally durable and practically indestructible. The Classic Rower doesn’t have any moving parts that can wear out, or belts and pulleys that need to be maintained.

The First Degree Fitness Challenge AR (Adjustable Resistance) is designed and engineered by professional rowers and craftsman using only the highest degree of quality components – ensuring complete satisfaction in function, performance, and reliability.  With its patented Fluid Technology, First Degree Fitness has incorporated the truest emulation of sensation, sight, and sound of real on-water rowing captured in the private setting of your own home.

As with any fitness activity, it’s important to exercise with proper technique, however. The big muscles in the legs are where most of the workout action should be. Injury to the lower back can occur from bending too far forward in the row. It’s best to maintain a upright 90 degree angle to the rowing machine’s seat and slider bar. Using the legs for the motion rather than relying as heavily on the back or arms can help reduce the chance of muscle pulls or other related injuries. Always check with a physician before starting any new fitness regimen.
From a fitness perspective, the WaterRower Club 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.
This piece of finely tuned, hand-crafted, water-resistance workout equipment also sits at the top end of the rowing machine spectrum. Employing a water flywheel that helps to mimic the feel of rowing in actual water, the natural wood WaterRower Rowing Machine will bring you a smooth, yet challenging workout that is as tough as you want it to be. If rowing is one of the best exercises you can do for your body as far as natural motion with low to no-impact, then the WaterRower is one of the best machines to do it on.
Con's: Super bummed that for $1160 they couldn't include an internal ANT+ transponder and Heart Rate strap(sub $100 package). The foot straps are crap! Within the first 1000m of moderate rowing they loosen to the point of being able to pull foot out on Recovery of stroke(Yes, even with ball of foot down). I really wish the WaterCoach F.I.T. software for the S4 Monitor was macOS compatible. It'd be nice to able to customer program workouts on my MacBook Pro or iMac.
The advantages with air rowers is that there is smooth action; there is only small wear and tear to its mechanism; its automatic feature adjusts according to your rate of strokes; and there is a wide range of the resistance readily available in replicating the feel of rowing through the waters. The only disadvantage of this machine is that it tends to be noise indoors.
The main advantages of the water rower are that it has quiet operation; there is only little maintenance to do, the water only needs to be changed occasionally; many users love the whooshing sound of water in the tank; and its consistently smooth resistance at every stroke. Two disadvantages of this machine are it costs a lot than the air rower; and it tends to be larger in size compared to the other rowing machines.
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.
