As the semi-official Johnny Aline Seed (I used to give them away after
making a bulk purchase from Leon) I just have to chime in.
I've tested them for accuracy against everything, and they win. Better
than a Cheshire and about a tie with a laser -- except they don't have
the "laser error" that can sneak in.
I suspect folks just can't believe a $5 device can be as good as
anything else commonly available at much greater cost, but: believe it,
beaver.
