Today I ordered a Prodigy for my friend. He took a couple puffs off of mine and fell in love with it. I accidentally ordered a 510 instead of a 901. I tried to message them afterward the fact but I missed my life of opportunity. Either way the person who responded was very sympathetic and kind even though my order couldn't get fixed. Either way I still give them 2 thumbs up for the nicess given to me.
