I bought this receiver in 2xDVBS2+1xC/T2 variant and I added a hard drive.
So far the box works really great, I love it. Very fast zapping, great features. I'm using it also as miniDLNA server to stream music files to iPhone or my other A/V equipment supporting AirPlay and this feature works seamlessly.
I'm not yet so familiar with ENIGMA though to play with various images and I'm just using my first EGAMI image that came in the box from the shop owner - no real problems detected so far, some minor topic with remote that was not switching off the receiver to standby mode while staying in EPG mode or DVR player application. I'm not sure if such behaviour is image specific issue or is just Miracle HW specific?
I highly recommend this receiver, great price and it is much smaller then Premium Ultra.
