I've had many brands of computers on my family's many bikes and they've all worked fine, though sometimes they were in need of adjustment. The adjustment usually consists of moving the sensor ane/or magnet until they pass as close as possible to one another without touching (no clicking.) I don't know which end of the sensor is more sensitive, so I put mine where the magnet will pass by the center - not either end. It always works.

Sometimes something gets bumped - usually the sensor - and the computer stops sensing the magnet. I can usually adjust it without tools or new zip-ties. Every few years the batteries run down and I replace them.

The whole thing seems pretty simple and foolproof to me. I use wired. Why add another layer of complexity and more batteries to replace?
