This has been an all round welcome addition to my kit, and sits nicely on my Amaran 100d.
It's incredibly easy to both set-up and collapse, taking just a handful of seconds due a simple pop-and-lock method.
Having said that, this comes at the cost of storage. While incredibly lightweight, it's the same volume as a hefty tripod. Fortunately it comes with its own bag. It doesn't look out of place when thrown on top of my tripod bags for transit (just make sure you put it on top!).
It does come with a skirt, which I've had no need to use. While it doesn't look quite as elegant when attached, I do appreciate the ease of setup.
