Relevant?
I walked into a clients dental office, who has CEREC machine, the assistant was cooling a hot Emax crown in front of a fan. I panicked and ask her if she does that a lot. She stated "yes". I asked her. "Have you had cracking? ..... She says, "Only sometimes." Not me btw!
Here's the thing! I didn't say they were crap! I wasn't referring to your product! I said I hate those things! So when you've apologised I will reply! By the way if I had a pound/dollar for ever time I've heard this is the perfect/best I'd be a rich man! But not rich if I bought all these...
