Absolutely true to the original NES controller, I really enjoyed it for two weeks. Certainly wasn't any where near as rough on it as I was when I was ten either, but its buttons started to only function intermittently, and then it stopped working entirely. I suspect the USB power internal to the controller isn't connected anymore, and I'll probably get around to soldering it up at some point, but hardware troubleshooting is a bit beyond me.
Playing Zelda through again was worth the 30 bucks. I hope you make a sturdier one of these at some point, brilliant piece of hardware.
