I used one of those for a while, but I one day took it off and found that it actually left scratches and a indention on my valves. I switched to the Wessex on and like it much better. But they may have changed in the year since I've had one. In my opinion though, I'd still much rather have a metal one like the Wessex. What's the spacing between the nipples on the bottom of your valves? I can measure my water gutter and see if it'll fit your horn.
