Allura fiber cement siding

Does anyone have experience with Allura fiber cement siding?

An architectural client received a substitution request (Hardieboard was basis of design) for Allura. I have specified it in the past, but the architect says there are lawsuits over this product.

I have no experience with them, but am amused by this statement on https://allurausa.com:

“Long-lasting Allura products are built to last a decade without even breaking a sweat.”

A decade is not a long time in the life of a building. Do they start perspiring after 10 years?

First thing that came up in a google search

No idea what the reality is but it would make me a little uncomfortable.
