Due to the many positive recessions I have decided for the Smart MX05L. Unfortunately the start was a bit mixed: After first connecting the unit reported 'no signal', but this was due to a slightly older Antennendose that my 'old' Kathrein probably not interested, for the smart but not enough of the existing level. After removing the can then arrived promptly picture and sound, and to set up the favorites everything seemed OK, but regularly the Smart operation got out after about 1-2 hours. No picture, no sound. After I checked all connections and cables again, I turned to the service, which was sending me the latest software update. Lo and behold, since the device is running without any problems! Rapid switching times, good picture, the menu navigation is also ok (if you're building seen through the same times). Bad is the info line, as it has very little character, thus indicating the title of the program only partially. Strong need of improvement is the remote: far too small keys to small lettering. But all in all still a good device with a good price-performance ratio.
