The lightning McQueen is really fun! My son will sit there with it for 20-30 minutes!

As for the lock, yes I do. My husband is super paranoid but what sold him is that we can give it "guest codes" do they don't get our actual code and we can delete the guest codes as often as you need to so no one who shouldn't have access can't just walk in. My husband works weird hours sometimes coming home after midnight or gone overnight and I wasn't the best at remembering to lock the door so it's really, really nice not having to go back downstairs to lock the door if I forgot to until I had gotten into bed or he'll check when he's working and lock it for me (sounds creepier than it is lol, I'm just really forgetful and grew up in a house where we never locked the front door).
