Right here's the deal, you are building an arcade machine of some sort, you want the controls to work no matter what? Yeah? Well buy this, it's so easy to set up it's ridiculous, it works without a headache, you can reprogram the configuration to different letters to avoid conflicts without actually having to use your brain, it just works, no headache. You want 4 players well go buy the bigger one or even buy two of these if it makes you happy. But two, players, tons of buttons, all the usual stuff you want to have, this does the job, don't buy the cheap model that keeps appearing on ebay and all that, just do it right and but this.
