Check out their warranty. It's short and not worth anything for long, or
to a successor owner.

And if you need help from them at Unison by phone, skip it. They're not
interested. And besides you'll be punching buttons on the phone trying to
get to a warm-blooded human being until you're fidgety and exasperated.
Maybe they don't have any warm-blooded humans there anyway.

I have a bad magneto lead and was really just trying to buy a replacement.
They will play phone and e-mail tag with you, ask you stupid questions, then
shove you over into the corner.

The good old Bendix mags are looking much better to me. Besides, when you
replace a lead you don't have to go through a major operation swaging it
into the distributor cap.

And you know something else? I don't know how many Slick mags I have found
on airplanes with the cap backing off the mag because one or more of the
screws has backed out and fallen out of it. It's happened to me with my
personal aircraft twice.

Add that to your preflight list if you have Slick mags: "Check to see that
your distributor cap is still attached to the back of each magneto. Also
check to see that each of the three screws holding the harness onto each
magneto is tight and secure."

Does Slick have any competition? It sure as hell needs it.
