I had a mystery brand cheap used carbon bottle cage on one of my bikes last year. It was a similar wing design but the wings didn't wrap around as far and the lower protrusion that supports the bottle was a bit shorter. It was extremely light but rather flimsy. I had it mounted on the seat tube and one fine long ride, I had one of my tall bottles completely full of water mounted in it. I hit a good, hard bump and the bottle slipped DOWN, past the the little tongue that's supposed to keep the bottle up as the wings flexed too much and would have fallen out of the bottom had it not hit the other water bottle.
Needless to say, I emptied that bottle to get the weight out to finish the ride and promptly bought another, better quality bottle cage. Just as well, the two on the bike were mismatched anyways and it was already bugging me.
