Supacaz fly cages?

[AngryScientist]

anyone using these? i've had mixed luck with super shaped alloy cages over the years, but i like the looks of these - is the quality OK and the bottle retention + in/out action good?

any experience?

i have the fly in the carbon version on my mtb bike. its all good.
the bottle stays put, i drink water and the world keeps moving. :)
