Arrived on the date indicated or in 2 days !! Well packed !! Regarding the counter, easy to install just need to find the right angle of the leg of the receiver relative to the small ring (magnet) to be attached to a spoke of the wheel. So position, check the information on the phone, and finally set! Regarding the cadence sensor you must remove the pedal, as on any timer, to tell the truth I have not yet installed ... It's not my priority! In the cabinet, there is code to activate the pro version of the app is the Road Bike or Montain Bike, but not both, then test the app before activating 2. They are free with fewer features. Remember to adjust the diameter of your wheel, there is a site that gives Quebec the figure to put on, or otherwise take a meter, pull down, and make a full turn of the wheel with the valve in the landmark! For now my only complaint concerns the app and GPS function, because unfortunately he does not understand that I'm in the fields or woods so the app will connect to the nearest road! That's why I do not put 5 stars!
