I've got one- been using it for the past 500mi or so. Hasn't fallen out even when full. With practice, I'd say it's slightly harder to replace a bottle without looking than with a traditional cage, but it does give a little more clearance for removal from tighter frames (I'm using it on a 54cm S2). It helps if you avoid changing your grip on the bottle before putting it back- then it goes back in first try no problem. If nothing else it looks nice.

No connection with the maker.
