Vinyl plank flooring - snap lock with history of success?

Allure with Grip Strip from HoD. About $300 of material. Not recommended for installation in a non-climate controlled environment, but it's been through all 4 seasons twice now in the northeast now and it looks the same as these pics.







Leave a 1/4 inch gap around the edges and make sure NOTHING gets fastened through the vinyl into the subfloor. This means cutting around seats and sofa brackets etc and double stick taping the edge trim to the vinyl. The floor has to move as a unit, else it will buckle.
