I got one last week and it's good, real good. But like too good? So I'll never have to worry about bed adhesion, which is not a problem very often but is the most common problem on the stock textured PEI plate that the printer comes with. But with the cool plate I definitely don't have to worry about it. Conversely, I have to worry about getting my prints off the bed without damaging them.

I think what I'm learning is that some prints are more appropriate for one plate and others are better for the other.
