On this model it has an altimeter (calibrate) with height difference (positive), a thermometer, a lighting fast when pressing one of the buttons and that can be easily put on and off, in addition to regular duties. The only glitch concerning the small plastic piece sensible hold the magnet on a spoke of the wheel: he broke during installation. I fixed this magnet with electrical tape and glued the broken part and for possible future use; it would still be better to develop a more solid piece, older models offered a small metal open ring with which I have not had a problem. Apart from this boredom, the meter is easy to install, lightweight and readable (it even has a three-contrast force adjustment, I just good enough level 1).
