Review on Gray Plastic Parking Mat Guides for Garage Vehicles by Electriduct - Anti-Skid Car Safety Park Aid by Omar Obong

They are great - the slits allow water that would otherwise pool under them instead of evaporating - unless you live in a desert climate you will appreciate. Adhesive strips fix the device semi-permanently and prevent it from moving. Don't tape it until you've checked the actual position from all sides - just drive the car away and before you stop - pull it up and the tape strips will come off - and stick it back on - voila. Pay attention to what color you get. . I originally bought the gray ones - and they disappeared optically into the concrete floor. Hastily switched to yellow. As you drive into the garage the yellow stands out and gives me meaning while the gray is gone and difficult to see. Use this information however you see fit - I could see where you would like it to fit in rather than stand out.
