I have the device since December. Even my old battery it worked very well. One can clearly see how the charging status. Since I use Battery Grips for my cameras, I have to load always 2 batteries. The device is collapsible, so well packed and transported. So the docks are well protected from dust and other contamination. The car plug enables the use on the go - so really necessary. Now I've bought a EOS 650D. Unfortunately, the two enclosed docks did not fit. So I once wrote to the manufacturer for many of searching. The answer was very surprising - I got after a short time the dock needed sent. That's what I call service!
