Wei Ming Tan –
I bought the Sherwood Harrison Convertible Valve last month for my dive trips and it’s really easy to switch between DIN and yoke. Feels very solid and had no leaks during my dives. The handwheel grip is especially helpful when I’m wearing thick gloves.

I like the valve’s solid build and how it resists corrosion. However, the low-profile design sometimes makes it a bit hard to grip when my hands are cold. Overall, it’s still a great upgrade for my tank.
