Very good quality, good price, microprocessor controlled, very strong spark. Nice, neat wiring, too.

Can't think of any...

I like this unit much more than the MSD 6A. That is kind of a unfair comparison though, because the Holley is more expensive. But anyway, this unit puts out a very strong spark, I've shocked myself many times while adjusting the timing. Hurts a bunch. The wiring is simple and neat, the unit used WeatherPak plugs that are nice and easy to connect and disconnect. I also like the fact that it is microprocessor controlled, unlike the analog MSD 6A. Rev limiter is smooth.
