I just finished over 2000 prints on their Elegance paper on our 11880 and there wasn't a clunker in the bunch. They flattened out much more quickly than the Hahnemuhle German Etching Board I previously used and the client loved them.
I'm only on my second roll of their canvas, but so far it's been excellent.
Tested a sample box of this stuff in the past and found it all to be generally high quality, in line with Hahnemuhle/Legion/Crane/Innova. You mileage will vary depending on the printer and what you like.
