Initially I purchased this lock on its core functionality and design. My home is outfitted with many smart devices and they all are centrally controlled using Apple's HomeKit. This lock is one of the few HomeKit compatible locks that has a great design/look. Installation: When installing the lock it was a very simple as all parts were labeled clearly (part #s). With the instructional video embedded in the app, it made it very easy to follow and install. Manual Use: Once installed and powered up, it was very easy to use its manual functions - lock/unlocking was very smooth. Any reviews that say the lock jams or doesn't slide easily tells me that the user didn't follow the install instructions carefully. It specifically says that you have to ensure the strike/lock hole is clear for the lock to go in and out. Using the key digital keypad was very easy too. The 2 digit random "pre-code" is a great way to ensure your finger prints are not captured. Key pad is responsive. My house faces North so I don't have a problem with the sun hitting the keypad directly; however, I have heard of people having issues with this (confirmed lifetime warranty covers this). Software/iOS App Setup: when setting up the lock in the iOS Kwikset app, I immediately saw that the app was old (App store says last updated over a year ago). Even the basic screen size to accommodate the larger iPhone size screens (7, 8, X, etc.) have yet to be updated. It looks like the app was last designed for an iPhone 5 screen. However, if it was just app esthetics I would be ok. There is a definite issue with connectivity - both away and at home. After further researching the issue, and speaking to Kwikset's customer support directly, it appears that the issue is with Apple's iOS 12. Kwikset went on to say that the issue is not only with them its with all smart locks compatible with HomeKit. Kwikset advised that Apple is working with all lock manufacturers (i.e. August, Schlage, etc.) to resolve the issue. They even took my number and email to keep in contact when they have future updates on a resolution. My 4 star review is based off of the support the main issues are getting. I was able to get great feedback from their team and am hopeful that Apple will work closely with the manufacturers to resolve the issue. Once the issue is corrected, the lock is solid. (Hopefully they will resolve the UI layout too when fixing the connectivity issue.)

The install was straight forward with hardware to install it with the two standard lock designs. Mobile app is easy to use and the interface is simply with helpful cues. Overall look is great Bluetooth works well.

This lock far exceeded all my expectations, the ease from its installation until its programming, is simple and safe, is handled very much from HomeKit to Apple like from its App.

The batteries didn’t last as long as I would like on it. Works well makes it easy to unlock and lock. Sometimes a little slow to respond to wake up the screen to do an action. Overall very happy.

I had some difficulty using the app that goes with it but customer service was excellent and it turned out it was an apple phone issue not the lock app, All working well now and it looks great, My only issue that prevents 5 stars is the fact that to change codes or replace battery there are 4 very tiny screws that have to be removed. WHY ?? it's on the inside should just have a slide on. I could not see the screws well enough had to get my son in law to come remove the screws!
