This thing looks pretty indestructible.
I've seen one at a local B&M and even had the chance to try it and it pretty well built and sturdy. I like to call it the otterbox or lifeproof of mods that are currently in B&M's, and online at the moment. However I did find it interesting that even when I was in the process of purchasing one the shop employee mentioned numerous times how difficult it was to get the battery compartment screwed down and actually was not able to even do it with a brand new out of the box and if that screw isn't all the way down it makes the water resistant claim pointless, she also said that using it with the batteries I had in the mechanical mod I brought into the shop would not work with it. I love the design and idea of it but for that price it was at the shop I was in which was roughly $90 before tax I decided it would be worth it to spend the extra and get a vv/vw box mod built from a friend that makes box mods(even though it would be bigger size wise).
