Official controllers come in one shape, and one size. Most of us either aren't bothered by the fact, or have learned to work around it over the years. Being in the former camp, I've never really considered the need to help extend the grip of my standard controllers - after all, I have the small, soft hands of a pampered middle schooler. But the need is out there for some folks to find solutions that don't give their hands cramps during extended gaming sessions.
Enter Playbudz, a company aiming to find solutions to crampy hands with their rubber grip extenders. Just take note that your mileage may vary depending on the size of your paws.
