Looks better than it is. Glitches and faults, no HD sound formats

I have pretty high-end devices, thinking Based on the good reviews I will try inexpensive cable.
Visually I was not disappointed. The cables themselves make visually a very good impression.

I have several 3m and 10m version ordered by my devices (PS3, satellite receivers, Blu-Ray, etc.) on my Yamaha RV-A3020 continues to get on my Samsung TV UE55C8790 and my new projector Epson EH-TW 9100.

But at the first contact device, I found that the HDMI connector very loosely inserted in the devices.
Whether Beamer, Blu Ray, PS3 or TV, everything very shaky. I still herumprobiert few days.
All in 1080p resolution and 7.1 HD sound.
Whether I have connected directly to the receiver or Yamaha, I had constantly interference. Either a lot of the transfer of all (especially 3D) or I had green strips in the image. This both with 3m, and with the long 10m connection to the projector. Never mind if I used the TV, or projector. Disorders were the same for all devices and experiments.
In tone range to much that everything was transferred to 5.1, 7.1 and HD audio formats not go.
I have tried other "cheap cable" from Amazon. Some were even worse, some a little better.
Ultimately, I have all sent back and bought me a decent cable during local dealer. While this was often so expensive, but it all boils down perfectly and without any disturbances.
2 stars for the quick delivery by Amazon and the appearance of the cable.
Technically, however, unconvincing in my equipment and therefore returned.
