So they changed how you twist to open the spout. It's seriously much harder than the previous style. It's no longer a one handed, open it while it's still your cage affair. I used to keep my second one closed til I needed it. Now I keep both open on a ride.
The spout still gives a good flow, but I don't think you get as much as the previous style.
I got the clear and after a few rides, it was already getting the black scuff marks they get.
They look like I've had them for years.
Still a good bottle, but not a step forward in design.
