Ms. Zelda, you're doing 510's right? I'll defer. I have zero experience with those. Maybe they are more apt to death? Just wondering about that as Tweety just had one die from AZ Smokes and I thought it was an odd fluke thing. But perhaps 510's croak easier?
Inquiring minds want to know.
Have you ever had one just stop working? I alway figured they had a certain "lifespan" and then they just stop.
