I installed them in May '18. I can't say how they will hold up. Because of my work and the crappy weather in my part of the country this summer I have only been on my boat a couple of times since I put them in. When not in use the boat is covered. So far so good though.
There are couple of things I will say about them. The each wood pieces are attached to the plastic lattice at a couple of points. Depending on how the tile is trimmed, some of the wood pieces loose one connection and them may be able to turn on the lattice. For those pieces I just glued them to the lattice with 5200 to stop the turning.
Also, the wood is stained. It is a light wood (acacia I think). When trimmed, the cut edges are light vs. the stained part. When installed in my boat, you can't see the trimmed edges, so I didn't do anything about them.
