Having a blast with my supertwin. most responsive controller in my arsenal, better than my arcade stick I use through the seagull adapter. Feels pretty durable. Used it on plenty of 2 button games (Fatal Run, Basketbrawl, Tomcat, Choplifter, etc), and the vertical button configuration hasn't been an issue. The stick and buttons feel nice, very arcade-y. Did try the dual stick Robotron 2084, and its pretty darn fun. Does seem a little tight for two players, but definitely playable (tried it). All in all, very happy with the purchase, and would recommend.
