Works perfectly and an improvement on the original

Did this item work well with your project? What vehicle type are you using this for?
Bought this for my MGB Roadster at the recommendation of my mechanic after the original dizzy was providing a poor spark on 2 cylinders. Whilst this is a more costly upgrade the money appears justified and doesn't detract from the originality/period of the car. Some things just need to be upgraded for piece of mind!
