Islandman, We differ in the sense that I do think a Zerostat can work to do the job for which it is intended. My only point is that I don't know whether MY Zerostat is still working after more than 40 years, and I certainly don't know if a Chinese-made Zerostat is any better or worse than one made in England. Nor do I think one can answer that question without taking some measurements.
To complicate matters further, there are completely contradictory descriptions of how properly to use a Zerostat, to be found on the internet. One says to operate the trigger back and forth while holding the gun about 12 inches from the LP. Another says to operate the trigger slowly so not to activate the clicking sound, hold the trigger IN, and then slowly pull the gun away from the vicinity of the LP while very slowly releasing the trigger. Some folks say you can de-stat while the LP is on the platter, some say not. So, if the gun does not appear to be working perhaps the problem is the method. (I don't know myself which is correct, but the idea to hold the trigger IN while pulling the gun away from the LP makes some sense to me.)
