The part weighs 25 gr, is 19.5 cm of stretched long and everything is laid flat 1cm the highest point (the three USB connectors on their own). Everything works as described. The - understandable, but not for everyone immediately apparent - drawback is that the user must opt for the OTG port functions either OR to charge the device battery. In the state of OTG So the battery of the "operating device" is emptied while the connected USB devices can then be apparently supplied with external current (otherwise would have to be drained more quickly with me the battery - but know I do not do it!).
This also means that - can be connected no external keyboard that does not have a USB 2.0 port, but even already brings a Micro USB plug connection - as in my case. At this point I was even inattentive - could be for me but not directly taken from the text. But on the other hand, most other devices are working properly with me. A Logitech Bluetooth mouse was directly involved and the touch screen could be continued use (based "Android 4.4 Kitkat"), a "normal keyboard" also, however, a "Natural Ergonomic Keyboard 4000" Microsoft refused to cooperate next.
The submission took place on packets in a luftgederten envelope, which was more than adequate and timely manner.
Other features I can not refer to the device itself, since in addition to (see product photo) printed markings otherwise has no label or markings.
