I'm very pleased with this lock. It's really useful for families with kids, because you don't have to worry about them losing their key. It also has some intelligent features ... when you press the top button (above the keypad), the keypad lights up ... if it's unlocked, pressing that same button above the keypad allows you to lock the door, without entering the code. I put it on my garage door, and I'm considering getting one for my front door, too.
