If you're shooting on a tripod, handheld or with a steadicam, it's great that it lets you use large batteries, but the moment you want to use a gimbal or NP batteries, it will it problematic . 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.
