This product was fully functional straight out of the box. All I had to do was put on the handlebars and away I went. The instructions were very easy to understand as well as for the remote. It was fully adjusted straight out of the box. I didn't have to do anything to it. Since all of the display is at your toes it's very easy to see what you're doing whether you're doing the time the calories the mileage. Very simple. Also, there's a spot on the handlebars for the remote just in case you wanna do an emergency stop it's right there in front of you. I found that the length of the machine was perfect for me, I'm short(5'0”) so the stride I had no problem with . It could probably accommodate somewhat taller, but that choice would have to be up to you. I found it to be perfect. I would highly recommend this machine.
