Received the Chinese ones today. Well boxed and packed. Very pretty matt carbon. Design very similar to the Lezyne Flow Side Cage, but much finer. No idea as yet how well they will behave - though they do seem to grip the bottle firmly and it is easy to pull the bottle out AND replace it - not always as simple as it should be with side cages.(Very light too - 22gm each).
edit: I don't like alloy cages as they mark bottles badly - I'd rather use plastic, even if they aren't as hard wearing, although the Lezyne plastic ones seem really tough.
