I am trailing the Stratus (thank you Bob) as we speak, it has the same click mechanism as the Vertex twist as Dan calls it. (nothing like renaming your products to get attention init?)
So far it has stood up exceptionally well, nice design to it, robust smooth click, platings holding out, can't fault it. (don't that make a change?)
Forgot to add that I did put one of Phil's refills in it to make a huge difference to the likeability of it.
