If you have a cup with LED Lights, the flashing lights draw attention faster to your cup to get a quicker refill. If you happen to drop them as you are walking or riding from bar to bar, they are also easy to spot.
A cup with a handle is handy to be able to fasten to your belt or backpack. Usually a leather strap or carabiner can connect your cup to your bag. A Keychain Ring and some Gaffer tape can also do the trick. This stainless steel mug is insulated and comes with a handy clip on carabiner for a handle. Just clip it on your belt, bag or ear.
