The LifeDrive HotSync+Charge cable works relatively well for my Treo 700w. I don't care that it doesn't have a sync button because my phone syncs automatically once it is connected. My only gripe is that whenever I connect my phone to my laptop, the files just seem to wander off every now and then. Maybe it has something to do with the automatic treo folder that's created with Autosync. I sync my phone frequently to transfer audio and Microsoft Office files back and forth, and the cable's been foolproof 98% of the time. The syncing function isn't stellar with Windows Media Player, but I'm sure that's just a software kink that Microsoft will have to work on. Overall, the cable provides a steady bang for the buck. You won't be disappointed.
