I've got Wahoo ones on the Red Baron, because it avoids some really awkward sensor mounting. No problems with the speed sensor (though note you'll have to improvise to mount it to a dynamo or gears-inna-can hub). The cadence sensor gives false readings on rough road surfaces, presumably because the entire front end of the bike shakes around like a utter bastard. On a brief test, It seems to work okay onna large-wheeled upwrong.
Main issue is the inconvenience of having to rotate the wheel and crank to wake the sensors (without derailling the chain), then tell the computer (Bontranger Node something or other) to look for them. You have to do that every time you stop for more than 5 minutes, and it's why wireless bike computers are an arse.
