I like it! The book is about the size of writing paper and is fairly thick- like a typical manga volume. The poses vary from standing cool with guns, fist fighting, throwing kicks, group fights, flipping, grabbing, to jumping. Most, if not all, poses have 2 versions: minimal coverage and suits. Great references for both muscle movement and clothing folds.
It's important to note that despite having loads of photos and angles, some images are kinda small. I recommend taking pictures with your phone to help zoom in on the details or draw over digitally.
