I have had this for over 6 months now and I have absolutely no complain. I looked at diagrams posted by users and set up was a breeze. The fasteners that came with it are still sturdy and keeps the wires in place so I don't have to worry. I love the fact that after each trip I make, I can reset the distance meter, time meter as well as the speed records so I can keep track of how long I ride and so forth...Battery hasn't been changed nothing has been changed and the product still works well...I LOVE IT!!!
