This is my 4th attempt at a cradle for my Palm Centro (AT&T). This is the first one that has worked immediately and consistently through the port replicator of my Dell laptop. It is a bit light-weight, but that hasn't proven to be an issue. The sync button has worked every time, and setting the Centro into the cradle is easier and less finicky that the others I have used. Charging seemed to be quite fast, even though it lacks an AC charger. This one is the keeper for me.
