Great gift but a couple things..
This was a Father's Day gift for my husband and it definitely made for a great gift. We recently took it to our local homebrewers meeting. When we arrived at the meeting we realized that the beer was bubbling out from where the top twisted on. The beer was, obviously, carbonated but once it settled all was fine. Make sure it doesn't get jostled much (any) on the way to wherever you're going.
Here are my husband's thoughts on it: I thought it worked well in place of a growler….definitely easier to carry and pour from. You just have to be sure you will drink everything you put in it that day because there is a little air hole in the top that allows the C02 to escape so the beer is not going to stay carbonated as long as it would in a capped growler.
