How necessary is a zerostat gun?

I often use it before I play an LP when there is static, and I always use it after I play an LP so that dust stays off as I slide it back into the MOFI inner sleeve.

Samhar, Ha! Will try it on child at the earliest opportunity.

We rarely need them in Houston, it's not the heat, it's the ...

I use it on every disc as well. With the winter coming (I'm in NY), I keep a can of Static Guard on my rack and spray the carpet infront of my equipment rack and from listening chair to rack. It has gotten rid of the annoying static shocks (that, once in a while, actually shut my amps down).
