Has anyone tried Scorpion lifters?

[WHITE AND RED 69]

I have been reading all the threads on the cheap foreign made lifters that the major brands sell and was curious if anyone has tried a set of scorpion lifters? Made in the USA and sound like they are a great product.

I have heard nothing but good things about them, believe they make the summit brand ones also, I was going to put them in my vette, but I sold the car.
