Hi. It's holding up fine. Not shifting. Shortly after install in April we still had some freezing weather. There is one butt joint that separated slightly... oddly a piece that is only about 18" long, but it runs into my carpet transition strip so I can easily correct it when I get a chance. I might not have locked it fully. So that one gap where I didn't expect it and no gaps where I did expect it. But still, the rest is fine and the true test will be this next winter. I'm not certain it would stay together as well as a glued seam, but again that was my tradeoff for the ability to dismantle all or part of it if necessary.
