Very pleased with mine. The battery lasts less than an hour but with the PowerMoney I get about three and a half hours.
Don't rely on the altitude read out though. It was showing 6000+ feet when the altimeter was showing 2000 feet. A look out the window confirmed that it was not the altimeter which was wrong!
I even plotted a route to Ostend using the Fast Plan software. Off the chart for the last bit but still showed the bearing and the distance to destination.
