We have been happily using our RX800 Rower for a couple of weeks now & have to say it is brilliant. It provides an affordable option to a solid design with great resistance! It doesn't make any particularly loud noises that concern me rowing early in the morning before work waking up the neighbors either which is a massive plus, as some can be very loud! Gives more than enough feedback on the display too & provides some workouts if thats what you like as well. The only thing which stops me giving 5 stars, when spending a reasonable amount on gym equipment I did not expect it to come without the power cable. Yes you can operate on batteries, but I don't know why you would choose this option. In either case, most battery operated appliances come with batteries for setup. All in all, I didn't expect the first thing after a reasonable purchase would be to put my hand straight back in my pocket for a complete build! The only silver lining, you can use the rower without power, making it a great investment as should the panel break in the future and we don't want to replace it, it won't mean we have the replace our rower if we don't want to part with it. All in all, a very sturdy well made product!! Definitely read the instructions for assembly before you start though!
