I use this material on all of our homes, whether we need the 8inch or the 6inch. I have revisited some of our installs from 2022 and the material is holding up. Vevor does offer the 1 year warranty, not too sure how good that is, we have not had to send anything back due to faulty products. We have run into some issues with wire not having PVC on parts on the guard or offlinement so we typically just cut those pieces off or snip and start brand new minus a couple inches that weren't produced properly.
