Quality OK, price great!

The mechanical quality is OK. The antenna grinds something when it is screwed and they also bends very easily. The cover of the headphones / mic port has come to me in the first tour with the spark missing. Was probably determined not so mad. The accessories is quite cheap. The programming adapter contains a Prolific PL2303 Fake chip. To recognize the fact that he registers as Prolific PL2303, with the current Prolific driver but is not running. In Windows Device Manager then says "Error code 10". You have to look an old Prolific drivers on the Internet so that it'll work then.
Who has the problem: Search at Youtube to "fix error code 10 for Prolific PL 2303 (Working 100%)" and read to be seen in the video text file! According to data published in Internet measurements only 4 watts instead of the promised 5 come out. I let just that easily stand, but I believe that the Afu professionals have the honest measured.
All in all for the money a great device. If you want more quality must take much more Euros in his hand.
