I recently bought the Karcher and am very happy with it so far. It is used as a second TV.
The handling is good, the picture quality for such a small TV really good - and the price is unbeatable.
The only disadvantage that I've discovered so far is that the device has no automatic transmission scan, which takes place all the same programs at once and stores. You have to start the search anew each time, and then save the progam found (maybe I have not the appropriate procedure found in the operating instructions). But do not do that so often.
Therefore, a star less.
