Easy and fast install, whisper quiet.
Style: Traditional
Color: Black
When my very loud Kwikset 99140-024 started to disconnect daily, I found myself in the market for a new smart lock. Without doing much research, I purchased the Veise VE012W-K. I tried to install it over the weekend and had nothing but problems with the app and the device connecting to my wifi. Unfortunately, Veise does not have technical support over the weekend which I find quite odd as that is when I would think many are taking on projects like this. After killing most of my Saturday trying to get the Veise to work, I finally gave up and ordered eufy C30 for next day delivery on Amazon. I already had the eufy C210 for my back door and found it to be reliable, easy to setup and it worked seamlessly with Alexa. Since the new lock was for my front entry, I wanted a lock with a more traditional look, with actual buttons on the keypad. The C30 fit the bill quite nicely. I was amazed on how quick and simple the install and app setup was. I did not time it, but I am confident it took less than 5 minutes. Oh, I forgot to mention that the lock was on sale for under $70!!!! With other locks going for north of $200, this is an absolute steal. This lock does not have a fingerprint reader, but that was not something I thought I would use anyway. It has all the features I wanted as someone who had a lock for Kwikset smart lock for years. I already mentioned that the Kwikset was LOUD, but this lock is whisper quiet. I would highly recommend this smart lock!

Resolves adhd marriage problems
Style: Traditional
Color: Black
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.
Style: Traditional
Color: Black
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.

Was using batteries Until I call customer support and had them reset software
Style: Traditional
Color: Black
These are good locks that I all had rekeyed so that all of them use the same key. Easy to install and use. Had an issue with it going through batteries but called customer service and it seems to be working better with an update. Another issue we are running into is we have some set at auto lock. You can only set it for 3 min max before the auto lock. It would be nice you could set it for a longer time.

Highly recommend this lock!
Style: Traditional
Color: Nickel
I’ve been using the eufy Security Smart Lock C30 for a while now and it’s been a really solid upgrade from my regular deadbolt. One thing I really appreciate is that it hasn’t dropped the WiFi signal or lost connection since I installed it. It stays reliably connected, which is really important for a smart lock. The app is also very well built and easy to use. Everything is laid out clearly, so it’s simple to manage settings and check access. I like that it works with Alexa too, which makes it convenient to integrate with the rest of my smart home setup. Another feature I really like is being able to add multiple users and customize their access. You can give different people their own codes, which is great for family members or guests, and it’s easy to manage through the app. Installation was pretty straightforward as well. As long as you follow the instructions step by step, it’s not difficult to set up. Overall, it’s a reliable smart lock with good connectivity, a solid app, and useful access controls.

Easy to use and set up
Style: Traditional
Color: Black
We’ve purchased two of these and are quite happy. The only struggles installing were due to the age of our home - the bolt is larger than our old locks and requires some additional wood to be chiseled out of the door jamb to allow proper function. Not the locks fault and makes me feel like it is a better quality lock, just wanted to call that out. Integrated seamlessly with the eufy home app. We love being able to unlock the door from the car when we’ll have groceries or something, or when it is raining so you don’t have to stand outside any longer than needed. Also allows remote unlocking - a family member stopped by the house when we were at work and we could simply lock and unlock for them from another city. Comes with physical keys as well so you have a backup. For the door that gets the most use, the batteries last a few months and you have tons of notice when it is time to replace them. Have never had an issue where we were locked out because the battery died, and even if you did you still have the physical keys. You can set up to 8 digits for the code, which I like. The buttons have held up well and the locks still look good a year later after install.
