[This review was collected as part of a promotion.] The home system I never knew I needed! I am currently redoing my mudroom and a new smart lock was a perfect addition! Very similar to the key less locks used at Air BnB’s, and easy to install. I love the feature of having an app on your phone to be able to unlock your door. Hands full of groceries? Unlock your door from your car! My only concern would be that the battery life only lasts for a certain amount of time. I believe a little over a year so after a year, you would have to change the battery I believe.

[This review was collected as part of a promotion.] Works perfect and easy to install! I have not had any issues with battery life yet it says a 14 month battery life and I’ve had it installed for about 2 weeks so I can’t say too much on battery life. The app is easy to use very simple straight forward. Comes with everything you need for quick easy installation. It auto locks if you forget.

[This review was collected as part of a promotion.] Wow! This is an amazing smart lock. It was super easy to install and is easily one of the best smart locks for the value. I’m not sure if it’s much more secure than a normal lock - I guess the fingerprint would make it harder to bypass though. Can’t say much about the battery power at this point. It’s been a couple of weeks and it’s still going strong for now, but we will see if that changes. I do think this is worth the price, especially for the ease of use. It also looks really cool once installed, dresses up the door and makes it look like we are putting a lot of effort into security (even if it’s just a lock).

[This review was collected as part of a promotion.] ⭐⭐⭐⭐⭐ The Eufy Smart Lock E31 is an absolute game-changer! The fingerprint unlocking is lightning-fast (less than a second), and it keeps getting smarter with each use. I love having multiple ways to unlock the door—fingerprint, Eufy app, keypad, voice commands (Siri, Alexa, Google Assistant), or even a physical key as a backup. One of the best things about this smart lock is its seamless compatibility with my existing smart home setup. It integrates effortlessly with Alexa, Google Assistant, and Siri, making it super easy to control access with voice commands. The real-time notifications and remote unlocking through the app are incredibly convenient, especially when I need to let someone in while I’m away. Installation was a breeze—only about 15 minutes with no drilling required—and the battery life (up to 14 months) is impressive. Even if the battery runs low, I can use a portable charger to power it up temporarily. The BHMA-certified durability and weatherproof design mean it holds up against all conditions, keeping my home secure year-round. If you’re looking for a smart lock that’s fast, secure, easy to install, and fully compatible with your smart home devices, the Eufy Smart Lock E31 is a perfect choice. Highly recommend!

[This review was collected as part of a promotion.] I have been quite impressed with the performance of the smart lock. The app connectivity is seamless, providing real-time notifications that enhance my awareness of access activities. I have not experienced any issues with unlocking, and the lock integrates effectively with my existing smart home system. However, I must note that the installation process did present certain challenges. Given the high quality of the product, the instructions could benefit from improved clarity, as I had to make several adjustments before achieving a successful installation. Once correctly installed, the lock has functioned flawlessly. The system has a sturdy, high-quality feel that adds to my appreciation for it. Regarding battery life, I have not encountered any problems so far, although it has only been a few weeks since installation. If the setup process had been more straightforward, I would have confidently rated this product a full five stars. Overall, I am very satisfied with my purchase.

[This review was collected as part of a promotion.] I haven’t had a Smart Lock before. At first, the kit included everything you need to install the lock. Also there is kit of keys for the lock if you want to use it on the old man. It’s easy to install. I like that I can give access to my house remotely and I still don’t have to carry those keys from the kitchen. Can’t say anything about the battery life yet except that it’s here. I think the price to quality ratio of this lock is excellent

[This review was collected as part of a promotion.] This smart lock was easy to install and it paired well with the App. I had no issues with removing my old lock and installing this new lock which was a pleasant surprise. It's great for feeling secure in the house and also when leaving so it gives a sense of extra protection. It works well with the app and it's a plus when I have friends/family that come over because I can give them a code to come in, instead of finding a spare house key.

[This review was collected as part of a promotion.] We love our new Eufy smart lock! It was easy to install, even on our older door. It gives us peace of mind to be able to lock the door through the app. I’m someone always wondering, “did I remember to lock the door?” And this solves that worry! We are looking forward to being able to remotely lock and unlock the door for family and friends. It looks sleek and the buttons are easy to push. This is a product we are so happy to have!
