Anybody have feedback on the Varivalve by Heat Timer?

Seems to be a efficient way to vent a One Pipe system.

    We find them to be

    very good. The fixed orifice Gorton's though are as good a choice as well. Larger chamber for water vapor to slow down enough to never get ejected and the fixed rather than variable setting prevents owner "twiddling" which can negate a decent vent system from working at all!

    The tendency seems to be to set each vari-vent too far open - resulting in oversized or close to the boiler rads to overheat (or make it appear the others underheat) and create as many problems as they cure...
