Although I have no doubt that this device will be great for driveway markers that are not solid or sturdy enough on it's own to insert into the adjacent ground, it will only accommodate a certain size marker rod. I made the mistake of purchasing this product because of the suggestion to buy it along with the driveway markers I purchased which were metal and thicker diameter than the fiberglass markers. I've decided to keep it anyways in case I have the need to use those smaller diameter fiberglass markers. Too bad that there wasn't the description included that it only fits a certain diameter size marker.
