I got one, for a good price, off of evilbay.
Just like collecting tools.
Uses two AAA batteries. It turns off after 30 seconds to save power.
There are 11 feed speeds. Low, 1 to 9, and high.
To use low and high, you just press those buttons.
To use the other 9 speeds, the number will appear between the arrows, you press the up/down arrows to the number you want, and press the Variable button.
I could easily feed .1 grains by pressing low.
The clear tube makes it easy to see the powder moving.
The feed tube is a little to high for me.
Had to put the scale on a book so the powder didn't fall so far.
Found it gave the best accuracy this way.
To empty it is kind of a pain.
I hold a finger to close the tube, then dump the reservoir. then dump the tube.
Tube is so long making it hard to do all at once.
So far I like it. It does what it suppose to do.
