If you're shooting with a tripod, handheld camera or steadicam, it's great that you can use large batteries with it, but once you want to use the stabilizer or NP batteries, that's it tedious. I mostly use mine on a gimbal so I probably wouldn't use it that often. I wish there was a quick release plate on the top of the box so you could at least have the option of using NP batteries. Indeed, this is a more permanent situation and cannot be changed quickly. And yes, the supplied Allen key is too short.
