spotted these in my Sainsburys today-a micro usb cable that has a keyring attachment so it can always be close to hand to plug into a computer/plug in charger. (they had lightning ones for the same price)
I'm always getting to work & cursing myself for falling asleep the previous night before putting my phone on charge. Or going out somewhere and using my phone more than usual and losing charge. So thought this might be a handy doodad to keep around for such occasions-better than keeping a long tangly cable lying around!
Not sure i'll actually attach it to my keys personally, but then I have a lot of keys so try not to have anything else attached bulking them up.
Anywho..thought it seemed like a good little thing. possible cheap little thing for fathers day?
