Title: Very Satisfied Customer
Review: Rapid delivery; easy to carry; leak-proof as advertised--the only times it has leaked has been because I failed to put the top back on correctly. The deep groove in the top that makes it so tight fitting is, however, hard to clean, and it appears it could harbor bacteria if you do not make sure it is cleaned thoroughly.
