I'm not a cyclist, so can't comment on their expertise or most of their equipment - I'm reviewing them because they stock and sell Clean Bottles!
Drink bottles designed by cyclists, for cyclists - both ends screw off and the drinking flange pulls out easily to be cleaned also.
I was devastated when the only (so I thought) Australian supplier stopped selling them - was delighted to find them here after ringing around a lot.
Today they had them on sale - $10.90 instead of, I think, $15.90, and it's the second time I've been in recently to buy them.
They've been friendly and enthusiastic both times, and I have no complaints.

Approximate cost: $10.90
