Product quality is far from great in my opinion... why ? 1) Computer mounting is really weak - you need to install and uninstall computer very carefully. 2) Magnet from sensor mounted at spoke on the wheels - this is the worst element of whole set. It's impossible to mount magnet on spoke in stabilise position (this element should include not plastic cap to secure but solid metal bolt). 3) Computer is for all the time on "stand-by" mode - it means that screen never turn OFF, it shows for all the time our current time. Last time Purchase.
