My original Padrone+ was defective and Cateye promptly sent out a replacement. This computer programmed perfectly out of the box and it works great. I tested it against my truck odometer and it is very accurate. It is a precise and quality device. The computer can be easily removed and replaced for security purposes.
If it is setup properly it will render correct readings. It is important to program the right wheel size for accuracy. My wheel size was not indicated on the chart but the Cateye site has an effective calculator which I used. If your headlight is too close to the computer it will interfere (only while flashing but not when it is a solid light) with its readings. My sensor device is attached to the right front fork so I moved the headlight as far left as possible on the handlebar and absolutely no interference. Really like the ease of using this computer for going to the different functions and especially appreciate the easy-to-read screen and the backlight. I am planning on doing an upcoming 25 mile ride sponsored by our local University and looking forward to recording the results! I want to thank D.J. at Cateye for his excellent guidance and help thru this process.
