Seems to be a fairly light and reasonable design, but it doesn't work. I find the supplied rubber pad too thick. With the seal I have no gas flow. With this, the gas flow is large, but there are many gas leaks in the tank valve. I'll buy a thinner washer at the hardware store and see if that solves the problem, but buying here was the only point I didn't have to go to the hardware store. If a thinner shim doesn't help, I'll definitely send it back.
