Got these to use with JBL PRX815w, or any other pole mount speaker I want! They are heavy! But that's what I wanted, so that I don't worry about my speaker falling over when lifted, and there is wind, and people around. The crank mechanism works smoothly. the handle folds away, but is still a bit bulk. You don't have to worry about using those silly pins for safety like with cheap stands. nice finish too. I got K&M 21312 Robust Carry Bag , to use with it, happy so far!
