i am drawn to this thread, it's magnetic, and feeling the static gives me a charge.
How long will it last?
One can reasonably expect on the order of 10,000 such "squeeze cycles" during the lifetime of a Zerostat 3 unit, although the typical Zerostat 3 will last much longer, sometimes as long as up to 50,000 trigger squeezes. The Zerostat 3 needs no batteries or electrical supply nor does it contain any radioactive components.
if you have an older one it might not last as long or offer the same number of effective squeezes.
