Treelabs, the folks bringing you the only "pure audio" bluetooth speaker has a special for one day only.
For just November the 11th, the first 200 people who choose to, can have up to 20 characters engraved on their own speaker for just $145USD.
What would you put on your speaker? "Hands off, don't touch" ... that's 22 tho'... Writing a tweet is difficult enough for me, let alone 1/7th. But getting something as boring as "Ryan Moore" wouldn't suffice it for this kind of speaker.
