Every summer we come across a new bottle opening gadget, whether it's attached to a phone case or looks like a kitten. However, this is probably the most handy and sensible one we've ever seen...

The Beer Tracker opens up your bottles for you, but also keeps track of how many you've consumed throughout the night. So, assuming you can still see the numbers, you'll know when you've had one too many.

Available from FredFlare for $10.
