Exactly what I was hoping for!
I absolutely love this.  It has the perfect amount of weight, is a great size, and is just so much fun to play with.  I've played with mine several times since it came in yesterday.  It fits easily in a pocket and makes a minimal amount of noise so I know I won't be pestering others with it while I fidget.  I'm tempted to now splurge and buy the larger version to keep at my desk for when I'm trapped during long phone calls.
