"Normally," has a USB cable USB-A connector for connection to the computer and a (Mini / Micro) USB B connector for connection to the terminal.
In this way it is ensured that the user does not accidentally connect two computers together, thereby possibly destroying the device.
But this case has the same USB-A connector, which can be found again on the computer.
The operation of this case therefore need an extremely unusual cable with USB-A connectors on both ends, which is so not x-fold found in the separate cable tray and in which there will probably be replacement problems, if it is lost time / broken is.
It also allows the inexperienced user to destroy his computer (s) - you can easily connect for example a USB power adapter to the USB port of his computer with this cable. The "fool security" of USB - what you can to each other plugs, normally can not hurt each other - is made as naught.
The housing appears to function and is stable. Bezel and back are made of black plastic, the rest is aluminum.
The hard drive is easy to install, the very small screws are very small, but a very small screwdriver is included.
So if you're ready, this shortcoming offset (USB-A to USB-A) to the low price and just want some old hard drives pack clean, the purchase is certainly justified. For convenience, I'll keep this oddity well.
I still wonder how to get the idea to build something - probably had accidentally a bunch of USB A-type connectors ordered too much and was willing to take the risk of trouble with the owners of the USB standard.
A USB logo emblazoned namely on the case - even though that's probably not justified.
