Apart from a scratch on the back caused by me opening the package with a knife (doh!) it’s a great lid for £45 and my second Nitro lid in 18 months. Wifey has a black NV1400VX she’s happy with, I have a titanium X533V. Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
