great wireless altimeter/cyclometer
I had a German-made wireless VDO Z1 for many years. This newer M4.1 wireless version is smaller, has a backlight and simpler operation. Altimeter is great for hill climbs and mountains and checking steepness of hills. Batteries last over a year. Buttons work with gloves on. All-around great product and if it's like my last one, will last you 8-10 years. More altimeter functions than I care for, so scrolling is needed to find the measurement you want. 1/4 twist on/off handlebar for security. Temperature and time are nice features, too. Would buy it again.
