My biggest gripe is that it is impractical to use the phone because the connection is then permanently separated, tilts the connection, and it's over. In addition, it can be quite tricky part "infecting", thus lead nix with slowly in the direction of the terminal, and then everything goes as if by magic in the dark. The status of people is a nice gimmick, red when it is charging, blue when it's full. What is a bit odd - it lights up without a connected device, so also consumes power - albeit in the lowest possible amount.
After all, it is easy on the micro USB port and the cap of the Xperia Z3, because you this now not always open / close must. Since I use quite a lot of my phone, a charging is min. Every two days required overnight if you sleep so it's an acceptable solution, albeit far from perfect. The price is unfortunately also seized some high under these circumstances.
