Yeah, I think the lenses are related to the M2 or MM, perhaps a better supplier was found. It's a good thing anyway.
Harsh, I'm not sure you can fault Mobius for the behavior you describe; AFAIK as all cap-equipped cams exhibit the same behavior. Like most things automotive, they're designed for petrol cars moreso than diesels since that's the largest part of the market by far. There are plenty of things in life where we must adjust our behavior to fit them in order to benefit from them, and this is just one more of those things. I've had to add "check the cams" to my list of things I do before the car moves an inch. Sometimes I forget that but I'm improving
