We found the sturdiness, weight and relief of not having to bump ourselves into the driveway to be a real treat! The builder in our subdivision began by creating proper curb cuts for driveways, but then "cheapened out" as the construction project was drawing to a close, leaving our entire street with these bothersome driveways. Besides our home, our vehicles are our most costly purchases, so we wanted to save wear and tear on them as best we could. The weight of these makes it unnecessary to attach them in our area, and we will remove them for the infrequent snowplow passes in the winter. The ruggedness, reflective stripes and smoothness they give to our driveway are a huge benefit over what the builder provided. These ramps fill the gap nicely.
