I've had this for about a week now and I've gotta say it's an excellent product.
The assembly took about an hour, there were some comments on the instructions. The only thing that took me a moment is the "A" screws are the two pieces at the bottom of the package, kind of a screw and nut.
As others had indicated I enjoy the sound, the swirling water sound is more pleasant than the air noise you get on a typical rower.
I really like the rollers on the seat, sometimes they'll have metal on metal where it has this almost gritty slide. These are so smooth you don't get any of that sliding back and forth.
It also looks amazing.
I couldn't be happier with the purchase.
