Product seems to do the basics, earning three stars; I cannot comment on the spare battery charger, having not tried it. Coming from the Blackberry world, where there are some very nice, easy charging stands for my BB Bold, I was looking for the equivalent for my Nexus One, feeding power into what appear to be charging points on the body of the phone. What I got instead was a stand with a clumsy USB plug feeding into the phone. I don't know if the problem is a design limitation of the Nexus One or just this stand. It takes the usual micro-USB fumbling to get the connector into the socket, a frustrating disappointment, but it does work. I don't bother taking this traveling with me, since it's just as easy to use the USB cable directly and prop the Nexus up on whatever's handy.
