I had done my homework studying all major brands of rowers before buying this machine last week. Dynamic R1 is by far the best in the market for a $1300 value and costco offer is an amazing deal. It's light weight but sturdy body. Assembly is easy in 3-4 steps, will not take more than 15 min. The control panel is very user friendly and 6-8 preset profiles are very helpful. moves very smoothly on the wheels. Folding and setup is very convenient because of light weight of the main chassis. The customer service is extremely helpful if you have any questions. One of my best purchases!
