A bottle cage that doesn’t fit any diameter of round bottle. How on earth does a manufacturer make thousands of these things without checking to see if a bottle (any bottle) fits? The front curved rail is formed into a tight radius, such that the back support is too far away to support a bottle of the diameter that fits the front rail. Yeah, you can stuff a bottle in there, but it’s not held securely. I cannibalised the thing for another project. Please just make things properly!
