I've got the gt40s and am very happy with it. When I was doing my research some of the reviews for the zr8 commented on the display being a bit simple compared to the gt40. Also more comparisons were made to the gt40 being more like a gym machine than a home machine. It is heavy but feels like it's very good quality. Also lack of drinks holder on the zr8 put me off..
but which is better?
What's the difference between this and the Reebok ZR8 that's about £40 more?
Does it have a tray to put my chips on?
