It has to be assembled, but adequate (not great) tools are provided in the packaging. Works great, but you have to provide batteries if you want to use the little counter/computer doodad. Smooth operation, solid construction, adjustable difficulty, etc. I use it every day.
Hey every one ! I got this for Xmas and was excited till I opened up the box. All the plastic parts were broken or cracked including the seat. I managed to get it to work by using some duck tape though. It's not a bad design . It has a long glide and that's good cause my legs are long. The "arms" for rowing track well and have a good resistance that is very well adjusted for ones level. They should fix the plastic parts .
