I have the rower, the Peloton Bike, and Tread. The Peloton has a far superior user interface, the app also runs significantly fast. Nordic track UI is slow and clunky, you have to wait until you select a class and start the warm-up to connect Bluetooth devices. When you do connect, you hear you have connected to "extra memory" instead of connected to your device. The Pelotons tell me which device I have actually connected to. When selecting classes, you can't just search for rowing classes, it's literally now an option. That said, the rowing machine is nice and smooth, and well-built. That said, ill be selling it and buying the Peloton just because the UI sucks so bad.
I did so much research before purchasing and made the commitment for the RW900 ... I got it delv'd and put it together myself --- It was pretty easy straightforward for the assembly, only issue --- it is very heavy so 2 people carrying in the box is a must!
I have been using it now a bit over 30 days and working out every other day ... I love it. What a complete workout and feeling good by it. iFit is nice and doing well for me. Overall I love this machine and will continue to use it! I hope to see some great results in some time down the road!
