There are some bugs, and I have reported some of them and also made suggestions for improvements. Chessnut are very active in solving and improving the machine so I have a positive feeling about being an owner. They have for example greatly improved the Maia engine that now plays a very good game of chess suitable for beginners to advanced players. I would also agree with you about the plastic pieces, they fit well with the design of the machine. I like their design and weight. Overall, I think the Evo is a very interesting device and very good for training/learning but with the ability to install other chess programs such as DroidFish and PGNMaster is an excellent analysis tool and database system.
