For the price / performance ratio there by my side 5 Stars.
The Appreciation I lay yet on 3 star ("not bad"), because you just have to accept certain limitations for the price. I want to say but clearly because of Fairniss: because of product reviews here I knew what I was getting myself and so I was not unpleasantly surprised.
Here is my list of abnormalities, but not limit the functionality:
Voice quality:
I have already experienced much better at telephone receivers and even mobile phones. For me a clear noise in the Hörnmuschel be heard. Of course, one understands his interlocutor, but the judgment "good voice" (which was partially awarded here) I can not follow personally.
I would say: well
Charging time:
16h to 2x400mAh loading .. wow - because it's certainly faster, the time to throw up in a charger!
However, since the phone is usually then still plugged into the charging station does not fall on the next. Since it is commercially available batteries, they are also good at least to exchange.
I would say: enough
Standby:
I do not know whether this indicated 100h really agree - come to me 4 days for a total of 16h load a little bit ago. But you can certainly take more capacity and if necessary extend the standby time. Therefore
I would say: well
"Blue backlit display"
I find it very hard to read.
I would say: poor
I welcome:
Accessories complete, commercially available batteries, good manual, basic functions
One particularly positive development: price!
