Just a note: I had one unit ordered and waited a month for it to be dispached, which did not happen. Complained to AliExpress and got a refund.
I think these devices are made "just in time" and even so it takes ages, probably for the required parts to arrive to the manufacturer.
Not the best experience...
I can only recommend the fake Agilent USB adpaters. Bought one and it works flawless so far.
