I was very interested in AD for a few years but reported problems kept me away. After I heard that much of the reliability problem has been solved plus local dealer was changed I was reconsidering it again.However, over the past 1 year, I knew of at least 2 of 4 units that my friends bought that still needed to be sent back to Germany for repair within 3 months after purchasing and local dealer only gave 1 year warranty (I assume that meant he will only cover the cost of shipping back and forward for 1 year) so I hesitated again. I like the result of its cleaning but I would really hate to be an owner of a unit that would need to take a trip here and there! Klaudio definitely looks more promising, less moving parts etc but have not heard much about other people's experience yet.
