I had a 1609 (wireless) for years. I like that it didn't lose it's info when I changed the batteries.
My MagicShine light as well as my mintyboost usb battery extender interfered with the wireless transmission.
It was a bit hard to remember what the 4 buttons did at first
You have remember to hit "start" each ride, unlike Cateye and other computers I've had.

That said, I still liked it a lot. I used it to track total miles. Now that I use my Garmin and Strava I log everything that way.
