Hi Mark!

In my opinion the Mephisto Milano is a very reliable chess computer, offering a solid and interesting playing style as well as a noticable understanding of endgames, if compared to other "Elo 2000 machines". It has an adjustable playing strength from approximately Elo 1000 up to Elo 2000 and offers almost any level you may imagine. Even club players around Elo 1800 and above will not easily beat this program.

Concerning battery consumption I unfortunately never tested this machine, but during my own tournaments the Milano was able to manage several games in a row, while just being powered by rechargeable batteries. I guess, it will run at least 15 till 20 hours continously if you take alcaline batteries.

Best regards, Willi
