Solid piece of kit. Ignore the trolls and whiners.
Built to last. It seals great and, while easy to open, there is little or no chance that it will come open accidentally in my bag or pocket. Also, once you have it in your hand, you will see why this closure system is better than a threaded closure. PS: I like the boar/warthog logo. Reminds me of Bebop from TMNT.
Would recommend to a friend.
