My brother has a grim history when it comes to gadgets and laundry day. One of his ipods was dead after a quick swim in the washer and his current cellphone can't recognize the 5 and 7 key after being washed too. So I got him and my dad, who recently found out had similar stories about gadgets and water, a thirsty bag. I can only hope they don't get to use them.
It's too late for all of my brothers gadgets, this is only a preventive measure for his current ipod.
I say, keep some of these bags around the house. Better safe than sorry :D
