Nice! Mine is probably around 8 years old now. I had one section pull apart like you were saying, so maybe not user error. I ended up pulling up that section, replacing any price that seemed suspect, and glued the joints during reinstallation. That’s actually what drove me to replace all the old T mold thresholds. But yeah, just that one defect across 900SqFt (84 SqM) isn’t bad.
