Ok. So the difference with the OOPS is that it purges the air when you turn it off I think, but as long as there's a hole so the air has somewhere to go when it's being unscrewed it should be fine. If the excess air comes out through the threads, it forces the bottle out and ends up stripping the threads. I've had this happen and it sucks. Can you confirm that this doesn't happen with this on/off? Bit annoying, I know.
