I really the shoulder buttons on the Brick despite everyone else seeming to hate them. Was never a fan of the slopes on other vertical handhelds and one other thing they do better is that L1 and R1 are the longer, bigger buttons as they should be. So many times I see these companies either make them the same size as L2 and R2 so they're not distinct, or even worse, make them smaller than L2 and R2 which is fucking awful. Still only second to the RG300's legendary shoulders though. And one of them fell off while inside my pocket once which spooked me into getting scared I might lose them one day.
