It does make a nice functional key fob. The micro USB sometimes pokes my hand when I reach in my pocket. It is also a conversation piece.
I love this!
I originally got this for my boyfriend, but after trying it out first, I had to keep it for myself and order him another one! It's so convenient and not too bulky. It's handy for the car or when you're out traveling. I love it!
I am so glad I found this. I travel a lot for the Army and having this, has made packing a bulky charger a thing of the past. Today you can find a USB port everywhere so now if my phone is about to die, no prob.
I just received mine today and it is currently plugged into my computer charging my phone. Works great, particularly in my house where chargers disappear regularly (lots of teenagers!). I'm thrilled!
