I don’t really buy many gadgets. I enjoy the iPod I got for my birthday, but that is mostly for storing music and podcasts. I rely on fairly standard phones and pc’s. I don’t use any devices to measure my progress when I walk or bicycle, either.
When it comes to beery gadgets, it’s mostly bottle openers and glasses. I have even pruned my beer glass collection to a minimum.
But sometimes there are inventions which come across as brilliant. Filling needs you did not know you had. The Maßkrughalter für das Fahrrad. for instance.
This is the invention of a group of Munich engineering students.
It is available online. Have a look at the technical specifications first, they have an adapter for older bike models. But you’ll probably have to go to Munich to get technical assistance from a properly attired Mädchen.
Thanks to lieblingsbier.de for the tip.
