Has anyone used either the Mannington Adura Distinctive Collection LockSolid vinyl planks (heirloom cherry) or the MetroFlor Engage Select planks (sunnyside cherry)? Any problems - especially with scratching from dogs? Also, I know Mannington planks are manufactured in the US. Does anyone know where the MetroFlor vinyl planks are manufactured? I'm trying to decide between the two so please let me know if you have any insight on either product.
