For years I go with this bike computer. Wind and weather he has defied and trouble-free working with my Shimano hub dynamo. Always easy to read in sunlight and rain. Also the GPS device use on tours could not affect its function. The battery runtimes were excellent long. I was very happy. Until recently, three new batteries in just 8 weeks due were: strange. A Radneukauf stood at anyway. And after some research, I've again opted for this product and it just fitted and tested. Worked right away, even with the SON hub dynamo. What have I to criticize? The settings in the Setup menu are not necessarily intuitive (4 keys). And more of a visual problem: The installation on the rigid fork requires an inclination of the transmitter part to the max. To realize 12mm distance to clock on the spokes.
