Although winter has yet to arrive, I bought this mat to replace my large boot tray as it takes up less space in a small condo entryway which has my door swinging inwards. I like that you can place the sliding grids in different positions and that you can easily wipe and wash the salt, and dirt slush off of the mat, and that it can be rolled away, or used without the grills during summer (sliding grills can be removed).
