The issues with Allure all seemed to be incorrect installation. The floor has to move as a unit when you're done. Also, there are 2 types; the planks that snap together and the planks that have adhesive (grip strip). I used the grip strip which glues all 4 edges to each other but not to the subfloor. It's been hot here for a few weeks and I'm not seeing any buckling. I put it down with temps in the 50s.
It was only $300 for the material. If I need to rip it up next spring and do something else so be it. It's so much cleaner than 20 year old carpet.
