If you're in the market for an extra-secure lock that you can open remotely, buy this one. Ease of setup: I have zero experience with home improvement type things - I’m normally a task-rabbit girlie. But I’m currently a bit poor, so had to suck it up and install it myself, and it truly was simple to do. If I can do it, any idiot can do it. Quality: It's good. I feel like you can't go wrong with a Eufy product. They may be a bit pricier than others, but they're always good quality. They look nice, feel nice, act nice, etc. Functionality: It works. One little plus is that it works even if the batteries are dead. I was out of town and needed someone to stop by my house. The app told me that the batteries had died and I was afraid the lock would stop working and they wouldn't be able to get in. I was pleasantly surprised that that was NOT the case! One (pretty obvious) thing to note: if you have a door that kind of sticks, make sure you shut it hard / all the way. This can't lock if the deadbolt isn’t lined up with the hole in the other side of the door. App: This can be controlled remotely from the app because the lock connects to wifi. I have another Eufy lock (one of the fancier ones with the fingerprint thing - which this one does NOT have) on my front door, and that one can only be unlocked with the app if you're close enough to it on bluetooth. Which is honestly so dumb, because if I was at home when I needed to open the door I'd just walk over and unlock it manually. This one however, is a major upgrade because I can unlock it from wherever I am! Game changing for if you need to let someone in while you're not home, but you don't want to give them your code. Just unlock it for them and then re-lock it when they leave!

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!

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 use eufy security on my property and I am very pleased with their products, so when I needed to change locks, I upgraded to these digital locks. As I have pets and I work odd schedules, my sons have to have keys to the house to feed and check on pets. This way each has their own code and I know who and when someone comes and goes. Also with the eufy app I can lock and unlock remotely, change and add who has access, and at a glance I can see if I remembered to lock the door when I left. Very easy install and sync with app and it works with Alexa. These require 4 AA batteries and seem to last a long while before needing changed, depending on which has the most use. Note: I bought rechargeable batteries just for this, that way I always have a set ready for when they need changing. The eufy app does give you a heads up when a locks battery is getting low. Good product.

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.

Great budget lock! We have had a touchpad Quikset deadbolt for many years that finally gave out. I think 10+ years of my boys yanking on it was finally enough. It thought it was locked when it was unlocked and vice versa. It had a good run. Thank you for your service. I shopped around a bit and wanted something secure but simple, high tech but affordable...and this Eufy seemed to fit the bill. We used to have an automatic vacuum from Eufy and it worked like a champ. So I had some brand familiarity and comfort with Eufy. This was a super easy install. It doesn't come with a full instruction manual so you have to scan a QR code to get to it. No biggy. It was all super intuitive and everything worked as stated. I did have to chisel out the recess where the deadbolt itself sits in the side of the door. But that was no biggy. Five minutes with a hammer and chisel after making a new outline with a pencil. Wifi integration was a snap through the app and so far everything is great. I've got it integrated with my google home and it seems to be running perfectly. Thanks Eufy for another great product!
