Size: Lock+ with Matter
Color: Matte Black
This is a really sleek product. It feels high end and well built. It was extremely easy to install which is great because I am not handy. User experience on the app feels almost too simple but after learning everything it’s a solid experience. It works great and helps me leave the keys behind and leaves one less thing for me to remember. The app is great and helps me keep track of everything. Easily connects to Apple HomeKit for easy set up.

The product was delivered in one day, ordered during prime day. The prudent is high quality, heavy duty metal locks without any plastic structure, come with a fob key that can be coded for the lock. I was able to add it easily to my Apple HomeKit and every time I use it send notification on my Apple tv and iPhones. Only issue I faced was that I had to call locksmith to fit it on my door since the deadbolt hole on my door was smaller than the Level lock. Overall happy with the purchase

Color: Polished Brass
This is a great-looking lock that doesn’t look like the usual bulky smart locks. It also comes in polished brass, which was important to match the rest of my home. Too many other brands don’t offer that option. It was very easy to install, and even with my slightly questionable door from the very early 20th century, it works great. Using it with Apple Home Key works perfectly every time. I feel good knowing that I can use my phone if I happen to forget my keys, and I like having the ability to use a key in case the lock battery dies. I don’t think that will be a problem since it alerts you to the battery level through the app, and it’s extremely easy to replace the battery. The only problems I’ve had are with Apple Home integration and the touch-to-lock/unlock feature. Even with the Level Connect wifi bridge, frequently, the lock shows “no response” in the Apple Home app, but if I open it in the Level app and then check the Apple Home app, it’s back. I also get alerts from Apple Home long after a lock or unlock event has occurred, but I don’t know why. The touch feature has failed the last few times I tried it, I guess because the app doesn’t know my location at the moment I’m trying it or something. I can just tap my iPhone to the door and it locks/unlocks immediately, though. I wish Level had Thread in the lock rather than the Connect bridge. Wi-Fi has never been as reliable or fast for smart home devices as Thread, at least for me. I do recommend this lock and your mileage may vary with the issues I’ve encountered. Overall, I’m pretty happy with this lock.

Stay away from this company and their products. I purchased a lock, worked fine for about a month, then nothing but connection issues after that. Back and forth for weeks with the company's support and they just drag out testing and retesting and will not replace. This company is destined to go under so look elsewhere for a product where the company will actually make it right when the product has an issue. Still having issues with this after sevel months. DO NOT BUY!!!!!!

One of the most striking features of the Level Lock+ is its discreet and seamless profile. Unlike other smart locks, the Level Lock+ is installed within the door, preserving the original look of your home's entryway. Installation is very straightforward. With minimal tools and expertise required, users can easily retrofit their doors with this intelligent lock, making it an ideal choice for both homeowners wanting piece of mind and convince from the smart features. Functionality-wise, the Level Lock+ includes a lot of the features you would expect. The app allows you to conveniently control access to their homes remotely, monitor lock status, and receive real-time notifications. It also is compatible with leading smart home ecosystems. Setting up with my existing Google Home was seamless. In terms of performance, the Level Lock+ has been reliable and responsive. The lock operates smoothly and quietly. The one down side is the battery performance, it uses a CR2 battery, and despite claims of a year, expect a few months at best with heavy usage. The Level Lock is a brilliant concept if your absolute priority is an invisible smart lock. The design is top-notch. However, the battery concerns and the concerning hollow bolt design (where the battery lives!) are things I would like to see In never versions. But even with those concerns the benefits the core functionality of smart lock and the ability to retrofit existing doors.
