Resolves adhd marriage problems
If you are tired of your adhd husband leaving the front door unlocked when he leaves for work before the sun comes up, this will solve all your problems. I no longer wake up angry and ready to start an argument about him inviting robbers in the house while I sleep. I was able to set up auto lock for the hours I know that he would be leaving and arriving home. Features I love are that you can unlock it remotely from anywhere (great for letting house sitters in and out), you can set up codes for all members of the family so you know who unlocked the door and at what time, you can set up notifications for when it was unlocked (perfect for toddlers that want to run for the horizon as soon as you close the bathroom door). The only complaint I have is that the battery life is lacking. In 4 months we have had to change the batteries twice already and this thing takes a lot of batteries!

Great lock, easy to set up for the whole family.
Great lock, easy to set up for the whole family. Installation was straightforward and took less than 30 minutes with just a screwdriver. The app is intuitive and allows you to create and manage multiple access codes for different family members. I particularly appreciate the auto-lock feature that activates after a customizable time period.Battery life has been impressive – going strong for three months now with regular use. The lock provides helpful notifications when batteries are running low. The keypad is responsive and backlit, making it easy to use at night.Integration with our smart home system was seamless, allowing us to check lock status remotely and incorporate it into our home automation routines. The guest access feature has been invaluable for visiting relatives and service providers.Overall, this smart lock provides excellent security with convenient features that our entire family has quickly adapted to using. Highly recommended for anyone looking to upgrade their home security system.

Take note of a couple things when buying this product.
Okay so far a good deadbolt but here are some things to know. When putting batteries into the deadbolt make sure they are 1.5 volt not 1.2. I also did some further digging and I think you can’t get rechargeable batteries for the deadbolt, however, if my research is correct you cannot use the NIMH. You have to use rechargeable lithium which are a little bit more spendy. There are rechargeable lithium batteries on Amazon that are over 4000 MW hours. I have yet to try it with the rechargeable batteries, but I do have a working. Here’s a second thing that you must be aware of. According to the on-screen directions when calibrating it says basically to clothes and lock the door. However, this may lead to the lock being unable to calibrate. Make sure there are no obstructions and that the path for the deadbolt itself is clear. If everything is clear and set right and it still does not calibrate, open the door and lock the deadbolt and then calibrate. This trick work for me as I was having problems calibrating even with proper batteries. Last thing is if you are planning on using this with Alexa, note that you’ll be using your Alexa 4 digit pan to lock and unlock the door and on the keypad will be the code that you set in the app for the deadbolt.

Great lock and easy setup
Easy set up and easy to use. Purchased this after returning another brand. App works well, and it is nice to have so many ways to lock and unlock the door. Being able to see its current status gives me peace of mind that the house is secure.

Easy to use
I love this door lock because I can easily change the passcode in the app. I also like how the lock button will turn blue once the lock is fully unlocked. It makes it easy for kids to know when to open the door before trying to open it too fast. I also like that you can see when it gets locked and unlocked in the app. This was easy to install

I’ve been happy with the Eufy C30. Battery life is decent and lasts at least a few months with fairly heavy usage. The install was easy. I like the physical buttons, auto lock feature, and that its WiFi connected. The price is fair for what you get.

This is my third eufy lock and second of this model. I put it on our vacation property so I can let people in and know if someone has locked or unlocked the door. Simple to install and setup. Works great as does the app. and the build quality is great.I do find you need to change the batteries every few months if it’s used a lot.

La verdad es que por el precio está súper bien, con el código ningún problema, con la llave y aplicación todo bien y con mi Apple Watch tarda un poco pero repito, por el precio vale la pena. La instalación es muy fácil.
