Seems a bit expensive - for a few bucks more you can get a cateye with cadence and if you dont need cadence you'll ge ta schwinn for much less. Never tried a schwinn but lots of guys here have good things to say about it.

Only thing lacking will be the backlight and scan features [I think the schwinn has the scan]

The cateye RD200 is fantastic and only 35 USD

Edit: Sorry - missed the wireless bit but you could still go thru the Amazon link
