Static grass applicators
« on: February 20, 2017, 07:47:55 PM »
I am seeing what looks like 2 kinds of static grass applicators with end shakers (not sieve cups open on the top).

They look alike, except that one is powered like a flashlight with 2 1.5 v batteries, and the other has a wall wart power supply that can supposedly be replaced with a 9v battery.

My first question is which performs better?

My second question is whether the corded power supply makes for better performance than the 9 v battery in the same unit.  It seems to me that having a cord on the end of one of these things is a negative feature unless it is needed for better performance.

Education, please.
