No matter how sophisticated the trackpads on our laptops get, mice are still irreplaceable because of the high freedom of movement and speed they offer. 

Padrone Ring is a small and nimble finger ring that can be used as a computer mouse.

This ring mouse connects to any device over low-energy Bluetooth and supports a variety of clicking and scrolling gestures.

More importantly, it comes in 12 different sizes and is waterproof, which means you can continue wearing it anywhere you go without worrying about breaking it or frying the internals.
