Now when I have friends over at night time to visit me, they can see my house number easy or better than that, I order pizza, they can find me faster. This sign comes with all different types of letters and numbers so I can use it for just about anything. I never have to put in batteries or wired for power since it is free power from the sun. I think it is made strong enough for any types of weather and will last for years. I highly recommend this item!!!
