The Pi is great, the bundle scrap

Amazon delivery was typically very fast. The Pi met expectations fully, the case is also OK, but the WLAN adapter of both supplies is simply scrap. Data throughput in addition to the router is so small that I could barely SSH send a command. On Video Streaming is not even thinking accordingly. A counter-check with an old stick EMTEC brought full reception and good throughput. Before anyone asks, there are 1.2 amperes at the PI of a USB adapter, so it is not even on the power supply.

From the seller you hear anything on the subject, so I'm going to contact the next step once Amazon.

Update:

After a few days the trader has sent me a discount and promised me a new drive to get delivered from another supplier. Accordingly, my problem has solved and the stars will be back! My thanks to Sam!
