(This review was collected as part of a promotion.) I love this deadbolt! Ours needed replacing and this one is great! It’s so sleek and modern. Installation was very easy! Took us about 10-15 minuets to install. I love that it takes four double A batteries instead of the smaller watch style ones. It’s customizable for your entry pin. And you can even set it to lock automatically after a set amount of time. It also has a smart key so you can keep using your current keys! Im so happy with this product!
