Please do not review"I wanted to buy a treadmill, but wasn't sure what to get because of my artificial knees... the staff was, first, very helpful online with a live chat and them when I called to order, more than helpful with picking out a machine that would be safe for my knees. I highly recommend Fitness blowout.com if you aren't sure what you should get." if you are affiliated or have a conflict of interest with this website.
