I have been using the Cat Eye CC-CD300DW for a couple of weeks now. Great wireless with cadence. I like the display that is clear and large enough to let you see speed, cadence, distance and time on one screen.

Manual is quite complicated (could to with a "quick sheet setup"), and it took me a few days to understand all the functions. (not sure though if I do today )

On the first ride, the dist stayed locked on ~41 miles for an unknown reason, I suspect I may have hit the "lap" button by mistake, or there was an interference. It has worked fine since.

Easy installation, quite complex set up. Handlebar bracket is "OK", design could be improved. Transmiter fits on LH chainstay with two straps, that is also something Cat Eye should improve.
