I bought this as a joke gift for my boyfriend for christmas and he absolutely loved it. I thought it would replace his annoying love of popping bubble wrap but unfortunately he says it is not quite as good!
Nevertheless he does admit it is still quite addictive and would happily it there popping it all day, especially for the "bonus" sounds it makes every 500 pops or so (even more annoying!)
He says that the only reason he does not use it as a keyring is because he would sit there popping it in his pocket all day long and he's sure to get a few weird looks!
Make sure you know what you're in for before you buy!!
