Very functional and good looking.
I really like that this smart lock uses a dedicated app to be able to remotely operate the lock and it also can send you a notification whenever the lock is operated. Now I know whenever anyone comes into or leaves my house. It also lets you issue guest codes to people you want to allow access to as well as letting anyone in remotely. I also dig the feature that can be turned on or off that will auto lock the door after a certain amount of time, up to 3 minutes. This is great because now I donât need to worry about kids forgetting to lock the door behind them. The app is quite functional and makes life easier. This lock is built well and looks good. The touch pad works well also and the ability to also use the included key is a great back up. This product is a very good deal for the price and I would recommend it to anyone. Eufy make some great products.

Quality design and unbeatable price!
I recently purchased this Eufy door lock on a whim because I needed a quick replacement for my broken Kwikset automatic lock. I had heard of Eufy before and knew their products were solidly made without a ridiculous price tag, so I decided to give it a try. And man, what a great spur-of-the-moment decision! Especially since we all know those impulse purchases donât always work out.Pros:⢠Sturdy and Durable: The lock looks great and feels incredibly solid, like it could withstand a lot of wear and tear.⢠Easy Installation: You donât need to be a handyman to install this. The process was straightforward, especially since my door was already pre-cut and universally sized.⢠Straightforward Connectivity: Setting up the smart features was pretty simple. While some tech-savviness might help, itâs not a difficult processâjust follow a few basic in-app steps, and integrating it with our Alexa ecosystem was smooth.⢠Convenient Code Management: I love how easy it is to add and remove multiple entry codes. This is super handy for us, especially when we need a dog sitter during our trips.Cons:⢠Aesthetic Size Preference: If I had to nitpick, I wish the lock was slightly larger, purely for aesthetic reasons.⢠Loose Turn Knob: The manual turn knob feels a bit loose. I tried making adjustments, but it seems like a manufacturing design rather than something related to my setup. However, once locked, the deadbolt is secure, which is the most important thing.⢠Hold-to-Confirm Feature: Iâm not a fan of the âhold to confirmâ feature for locking the door. Itâs not a huge deal, but having to hold the button for a few seconds to lock the door can be a little annoying, especially when youâre in a hurry. I wish there were more in-app options to adjust this, allowing for an instant lock with just a single tap.Overall:Iâm really impressed with this Eufy door lock. Itâs been a great addition to our home, and Iâll definitely consider purchasing more Eufy products in the future!

Would Recommend For The Price
I’ve had this deadbolt for about 6-7 months now and overall I’m pretty satisfied with it.Starting from the beginning, the price is pretty good I feel for this lock considering the build quality and reliability. Installation was pretty straight forward, setup was quick and easy, and I have not had any issues with connectivity or reliability. Has all the basic features i wanted without any unnecessary add-ons. Locks and unlocks smoothly, but that can be different if you don’t follow installation instruction. Deadbolt functions as you’d expect, locks and unlocks from app, keypad, and key all without issue and all with a simple process. Keypad doesn’t really get used at night but I’d say it’s most likely bright enough to be operated in dark conditions. Works with my Google Home setup and voice controls. App is easy to use and understand but always room for improvement.The reason for 4-stars and not 5 is its a little slow to unlock and lock from app, the delay is kind of long. Also, I could be forgetting how to do it, but i have to enter pin to lock it instead of something simple like a quick button press. I’d love to see some quick lock/unlock features on main screen in app or maybe a widget i can place on home or lock screen of my phone. Lastly, extremely minor and not important, but would be great if key was stamped with Eufy or a logo to help identify or differentiate it.

Very nice brand

This lock is advertised as capable of locking/unlocking via BT. This is not true. The customer service I contacted claimed application unlocking is what is meant by BT but it is not BT, it is wifi unlocking and clearly needs a connection to the company server. In other words, one has to be connected to the internet to unlock it from within application.After I stated this simply fact the agent got disconnected.
