Very reasonable easy to install and does its job well..Hard to ask for more than that for 30 Dollars. If you leave skid marks on your driveway-patio-sidewalk when you clear snow during the winter you need these. Simple 10minute install and height adjustment then your in business. If you buy them make sure you get the bolt kit inside as you need atleast 2 longer carriage bolts to install the slides as they are thicker than the original steel skids.
These even help to make it easier to move in the garage during the off season for repair-maintaince work.
pick up a set before the snow hits you'll thank yourself later
