Neat little design, still good if you use a case!
This item arrived in a nicely designed, solid cardboard, printed protective box. The box opened nicely to show a well laid out interior, with the transmitter protected in a plastic packet, with plastic sheets protecting the glossy front and back of the unit. Inside the box were the unit itself, a micro-USB cable, and a car cigarette lighter USB power adapter, along with a basic instruction manual.
I think it’s a nice touch that the power plug has a standard USB socket, so you can use it to either power your phone, or power the device. The device has a battery, and there is a battery level indicator in the display, so you can use it without it being constantly plugged in.
