On the problems of the previous speaker: It may very well change the order of channels. As mentioned by him you can create a favorites list and change the order of the channels at will. This list you have to then enable or select then the whole works well with the numeric buttons and the Prog + / -. Keys. We need maybe more than 5 minutes to understand the functionality of a device. ;-)
The buttons on the remote control to stay with me also not hang the way.
Also very positive: The Scart output is RGB compatible. Especially recommended for tube TVs for best picture quality. The second jack (input, looped through) support RGB, making it ideal for game consoles (switches automatically when external source is turned on).
Switching between programs is very fast, EPG is available and also quite fast, timer function is available. The booting the device takes about 5 seconds, so to cope with.
CONCLUSION: From me definitely a buy recommendation. Negative points are to me until now no Noticed. Well, except for the mandatory external power adapter. I hate these things, but are almost standard.
