Got them in a weak attempt to protect a set of controllers from children. The silicone is very thin so I wasn't expecting much. They work better than expected. They offer a bit of cushioning if the controllers are accidentally thrown, they offer a better grip preventing falls, and if the controllers break, they hold the plastic parts until they can be cleaned. If they keep the controllers going until we can teach the kids not to be so strict with them, they're worth it.
