I have this computer and a bunch of wired cateye computers on other bikes. I prefer the basic Cateye Mity 8...its cheaper and far more reliable than the wireless models. I think the wired models are more inconspicuos than the wireless ones. The wire is super tiny and nearly invisivle. In contrast, the Cateye Micro Wireless unit is like a huge box in comparison to the wired versions, and the sensor looks like a giant robot arm zip-tied to my fork blade. Plus the wireless models need batteries for both the unit and the sensor, and these batteries only last me about a year. I have five cateye wired computers on different bikes and none have ever failed, or even needed batter replacement. The oldest is more than 6 years old.
