Compared to CT-3650 CI: The T680C doesn't heat up (just under hand-warm), even after hours receiving HD-TV channels (720p). It has in general better reception than the CT-3650 and is able to recive all channels. CT-3650 had frequently problems on the same line and some of the channels could not be used without frequent bit errors. From my point of view the DVBSky T680C works much better and more reliable than the Technotrend CT-3650 CI.
 
 
Compared to my GRUNDIG Television (40 VLE 8221 BL): Signal quality of channels looks much better on the GRUNDIG by value, however the channels work exactly the same. The T680C shows less good signal value for some channels but is better able to decode them afterwards / less or none image scatter compared to the Grundig Televisions build-in DVB-C.

Test case - Hardware - Reception - Comparison

Used as DVB-C device connected to german cable provider Kabel BW (Unitymedia). Replaced a Technotrend TT-connect CT-3650 CI (hardware breakdown, seemed to die of overheating or something). Software used: Ubuntu 13.04 (amd64), TVHeadend and XBMC. PC is an Atom D525-based Zotac Z-Box ID-34 (NVidia ION).

Good reception and quick channel switches. Works very well. Scanning for channels in tvheadend didn't find all the channels at first scan, due to bad reception, however after manually mapping them they worked flawlessly.

Compared to CT-3650 CI: The T680C doesn't heat up (just under hand-warm), even after hours receiving HD-TV channels (720p). It has in general better reception than the CT-3650 and is able to recive all channels. CT-3650 had frequently problems on the same line and some of the channels could not be used without frequent bit errors. From my point of view the DVBSky T680C works much better and more reliable than the Technotrend CT-3650 CI.

Compared to my GRUNDIG Television (40 VLE 8221 BL): Signal quality of channels looks much better on the GRUNDIG by value, however the channels work exactly the same. The T680C shows less good signal value for some channels but is better able to decode them afterwards / less or none image scatter compared to the Grundig Televisions build-in DVB-C.

Seems to be good hardware.
