(This review was collected as part of a promotion.) I absolutely love the Weiser Powerbolt Deadbolt. It was sooo easy to install, took maybe 20 mins. I now feel at ease when my son comes home from school, and i don’t have to worry if he forgot his key. As well as i no longer have to carry around a large key chain while out on a walk. I am very very pleased and would 100% recommend this deadbolt to any and everyone!
