When you first plug it in it works for a day or two and then intermittently which is totally unreliable! Contacted AMZ and they sent me another one against my better judgement, but I let him talk me into it. Worked perfectly for about two weeks and then again with such interruptions that it is too unreliable! I bought these because of the high customer ratings, but they were all significantly over-salted. I'm sticking with it now as it falls outside the scope of the return policy. The problem seems to be that the solar panel and batteries are not working properly. I believe the batteries are not meant to be used and there is no way to replace them. At first I thought I moved it 20 feet too far from the driveway, and then I moved it 5 feet. Little helped, but there was an improvement. If it's a cloudy day or after sunset, it just doesn't work. A real waste of money, I'm so sorry I let the seller talk me into getting another replacement. I hope this helps others looking at this product.
