Hands-on: This modular controller slides open to transform your iPhone into a mobile game console [Video]

I first saw the Ohsnap MCON controller at CES last year, and I immediately fell in love with the concept. The idea was simple: give people a full-featured mobile controller that attaches to your phone via Magsafe, slides open when ready to use, and collapses into something compact that can go with you anywhere. Over the last two weeks, I have put it through its paces. I have tossed it around, pressed the launch mechanism 100s of times, used it with emulators, Apple Arcade games, and with multiple phones. Here is how it has held up, along with everything you need to know.
