Anyone tried one of these HEI Distributors?

I have the ProComp Chinese crap HEI with the coil in cap and at first had an install problem which I machined and made it slip right in. Its been in my 64 Signet for a year without a problem. Cost was cheap, my 360 roller motor runs excellent with it and I'm happy its there, BTW I gap the plugs @ .050 and it runs strong..
