I purchased the Steam Controller with cautious optimism, and I have to say that I am pleased overall. It is comfortable and flexible, if a little light. The biggest gripe you'll see online might be the ergonomic placement of some buttons/functions; but this is small concern for those willing to map functions themselves through the easy naviagation menu and transform the default arrangement into something more intuitive, personal and unique. If you believe that a controller should be a carbon copy of a console standard, then you will be initially disappointed. This is different by design and pairs the function of the keyboard and mouse into a handheld format-it isn't Xbox or PS4, and if they're your interest-they already do their own job really well! Your enjoyment of this device will vary based on your desire to take the time to arrange the set up and practice until muscle-memory kicks in. It isn't work, but for the institutionalised console gamer, it is a step BEFORE truly enjoying the gaming experience fully. The drawbacks for the controller itself would be shallow bumper buttons and gloss surface (easily addressed with some decal). The greatest positive is the flexibility of input and ability to map for titles traditionally not compatible with controllers.

This is not a pad for everyone, and it is use-oriented rather specifically. Am I going to use this for every game? No. This is a unique tool that you employ for certain tasks and I'll certainly be using my xbox360 wired for FPS or Arkham/Assassin's Creed style gameplay. However, for desktop or couch gaming with titles like Civ, indie titles, Elite or emulatiors there is no comparison.

Hope this helps!
