The eufy Security Smart Lock C30 was easy to install and very easy to use. The quality of the lock is excellent. It is easy to control the lock from the phone app. I installed two of these locks in my home two weeks ago and they are working flawlessly. The price for this lock is reasonable and the phone app is easy to use and works very well. I recommend this lock to anyone who is looking for a quality smart lock that isn't overly expensive.

I’m really impressed with this product. From the start, installation was super simple—I had it up and running in just a few minutes without needing any extra tools or complicated steps. The cost is very reasonable compared to other options I looked at, and honestly, I wasn’t expecting it to perform this well for the price. It feels like a great value. Day-to-day use has been smooth and straightforward. Everything works exactly as it should, no hassle. I also love how well it integrates with my smart home setup—it connected right away and responds quickly to commands. Overall, I’m really happy with it. Easy to install, affordable, simple to use, and smart home–friendly. Highly recommend!

Great product. Good value. I installed it myself - I didn't time it, but it was actually really quick. Works as it should, no problems at all. It's been on our front door for some time now, I'm thinking about getting another to replace the side door lock. The smart features are pretty cool, although I don't use them very often.

This product works as advertised and is responsive and opens and closes easily. It was really easy to install and the quality was good. The only issue I had was that the battery dies really quickly. I have tried two sets (different brand) and both seem to die rather quickly.

I absolutely love this smart lock. Setup was smooth, the app is intuitive, and being able to lock and unlock my door from anywhere still feels a little futuristic every time I do it. The keypad lights up perfectly at night, and the build quality feels sturdy and secure. I also appreciate the sleek design — it looks modern without being bulky. Whether I am coming home with groceries or letting someone in remotely, this lock has made life so much easier. Safe, smart, and seriously satisfying.

I had a pretty bad allergic reaction that made me stay in the hospital for a few hours and no one had the keys to my apartment to keep an eye on my dogs. Decided to get this just in case I had another incident of the sort. Ordered it from Amazon and it never arrived but I ended up getting it in person and it has been the best purchase I've ever made. The set up was easy, the lock functions well and it looks fancy. Only downside that it has is that it doesn't have battery included. However, I bought the rechargeable batteries and the battery last for almost 3 weeks. Im 27, live by myself, and I was able to install it without help.

First off this lock, especially for the price is awesome. I love that the exterior buttons are physical press vs digital. The locking mechanics feel smooth, and being able to do it from an app with a simple drag is just awesome. It was fairly easy to install, with some caveats. Everything went on easy besides the interior plate. For the life of me I could not get the included screws to thread into the mounting plate. I ended up having to use my old lock screws + one that came with the kit to screw into my door to hold it. This isn’t how it’s supposed to be, but it works. Second, adding users is kind of weird. I wanted my wife to have access to the app so I invited her via email as it prompts you too. Well it isn’t as easy as just sending an email for access like I’m use to with Amazon products. We had to get the email, make an account with that email, send the invite again now that the account was active, and then go to the Apps inbox to accept the invite. Just seemed like more steps than usual. Very minor flaws though and not enough to knock it down any stars. It’s awesome being able to set up multiple codes for parents, in-laws, whoever. It’s great to be able to unlock my house from my car and just walk right in. If you have a “dumb” lock, you’ll enjoy this upgrade.

The lock has a clean, basic finish and doesn’t offer as many advanced features as some of the higher-end models, but it does what it needs to do. The built-in WiFi is convenient and makes remote access easy without needing extra hubs. Setup is straightforward, the keypad responds well, and the app connection stays stable. It’s not packed with options, but for a simple, reliable smart lock with WiFi, it works just fine.
