I love the Halo Kwikset lock while using the Kwikset App, you can lock or unlock your deadbolt from your smart phone. Between your smart phone and the smart lock, using your wifi it allows you to execute commands from the Kwikset app. The command sent by your phone is communicated to the HALO smart lock via wifi. I love that I can use this app to check if anyone has been home. It was so easy to install. The only change I would make to the package as a whole would be to offer a two piece set that way I could have it on my front and back door I am sure they may sell it but we only got the one set.  I would Highly recommend buying this lock for that added protection everyone needs.
