Ideal for large rooms. It is fully adjustable to finish. The swivel ball adapter has held up so far, although this can be an issue with rough use. I use old Sony camcorder batteries (I swear they will never die), NP-50 lasts an hour and a big FP 70 lasts 3 hours. It also takes AA batteries, which I haven't tried. It's relatively small and easily fits in my camera bag. A necessary option for my 5D II. When I need to shoot an impromptu video, it's ready to go.
