overpriced and does nothing for a driveway that already has potholes. I've had one for 5 years now and unless you're willing to spend hours driving back and forth with little result I would stay away from this product. The battery is junk and has been replaced twice now. The rod that controls the up and down motion broke the 2nd year and was not cheap to replace. I'm sorry this thing is utilizing space in my barn that I could use for something else.
