The washers are a clever touch — they keep the keys from rattling against each other, which was my main annoyance with my old setup. Everything stacks onto the central post without any tools, and assembly really is as quick as advertised.

Took me under two minutes to stack everything onto the central post, and the washers keep the keys from jangling against each other, which I didn't expect. It's compact enough to disappear in my pocket now.

The washers and central post design make this thing honestly kind of fun to load up, and it took me less than a minute to get all six keys on. Everything stays flat in my pocket now, and it’s solid enough that I don’t worry about it popping open.
