Very weird new ignition coil problem

I took the tank off , the 2 and 3 coil is shot.
My multimeter read infinity on the primary, low voltage side.
I had to connect my old coil and the engine is running perfect again. Plenty of torque and smooth.
My question is: what can cause a new coil to break only after 800 miles? :blink:
It was a factory problem of the coil itself or i should search something else? Can a low voltage connection (maybe a bit loose) cause that?
Thank you, happy summer!

It's not that I'm cheap, it's that money isn't flowing like it did when I was still working full time. Semi Retired. :whistle:

Sometimes you just get a defective part. I had a coil that would cut out after about 30 minutes of running time. After it cooled down, it would fire again....it only measured 0.1 ohm out of spec when I checked it....

It happens in under 5 minutes (of non-continuous use of course, I've never gotten the bike to run yet).
It measures out close to but not exactly what the advert says it should (ie: I get 5 ohm, not 4 ohm readings but they are consistent with each other).
Basic problem of DOA, new part still remains an issue tho. I contacted the seller who eventually responded and told me this has never happened before. I can send it back (at my expense) and he will replace it.
This is the eBay item I bought:
[ Looks Stock(ish) but clearly NOT ]
One of the steepest learning curves with these old bikes has nothing to do with the bike itself but learning how to be a better online shopper (which I have failed multiple times now )

Higher resistance is usually okay, but lower than specified resistance for the particular ignition at hand could result in coil failure.
