Shopper 
(New Orleans, LA) - May 6, 2015
I bought this as a gift for a college graduate. The time for the sand to go through is always below an hour within a 12 minute period and never consistently, e.g., sometimes 48 minutes, sometimes 50, never over 52. While I realize this isn't a product with exact timing, I expected it to be closer to an hour than it is. Huge disappointment.
