(This review was collected as part of a promotion.) This product was very easy to install. It took my husband maybe 10 minutes.  we also programmed our current house keys to this lock which was awesome because I did not have to get new house keys cut. We had this installed for 3 weeks so far and have had zero issues. The app is working and the touch screen is working great. the app connection to the lock is awesome. It gets pretty cold here in the winter so I will be interested to see how it works in the cold winter (I will write another review on that). I definitely reccomend this lock as it is very convenient. I will for sure be purchasing a 2nd lock for my back door and one for my garage door as well. I would reccomend this lock to anyone in the process of building their homes or just wanting to switch their current lock with a convenient easy to use one.
