Coil early failure - why?

[Torchard]

Hi. I have a Mike’s dual output coil, The high energy version. It’s got no more than 10 hours on it and according to the multimeter it’s dead on the secondary side. As far as I know I didn’t tested ungrounded. Any thoughts on a reason why it might have had such a short life? I ask because I don’t want to replace it and just have the next one fail in short order. I see that particular one is out of stock at the moment so I’m looking for an alternative. Thanks for the wisdom. (I know this is a common enough thread but I can’t find something that speaks specifically to what I’m asking here.)

Not sure what those emoticons mean.

Some of the Mike'sXS coils have been notorious for shitting the bed.
The one's I pictured tended to fail when the primary terminals fell out of the body, happened to me (and others).

If you have the stock TCI ignition, a nice, cheap, very dependable replacement is a used Honda MP08 coil.

Thanks. Just ordered one. Staying away from those and similar listed above. (Also have a Polaris series regulator yet to be installed - it’s a bit of a brute.)
