Mihalis, It's a good thing you can send it back. You would have been disapointed if you had to keep it.
I however, really enjoy the Qol in my system and I have neither of the negatives you mention. I also think it is a very good looking unit with very good inputs and outputs. The bottons on my unit seem to be well made, so I am not sure what your complaint of them is, but they are rarely used because my Qol is always on.
I certainly don't doubt that you were not impressed by the Qol, but I'll keep mine.
