This unit is ideal - no tools required for mounting. The large suction cup holds to any clean, non-porous surface, for example, a windshield, console or dashboard. If you mount it and the rear-view is not satisfactory, simply remove and re-stick elsewhere. No holes to cover!

The mirror itself is 100mm (4 ) x 200mm (8 ) and is fully swivel adjustable. It is made of non-corrosive materials and is ok with salt spray. Body and other parts all black.
