Just picked one of these up myself, seems pretty nice for $40. I’ve had to play for a few days to figure it out though, I’ve zero experience with these. This may be helpful.

You should get the cable to at least set the password to it. You can pick up an HP one for a few dollars. If you have problems later with the password you can wipe it by holding the clear button for 1 second.
There is definitely a learning curve with this thing!!
