    • Good quality, good price
Color: Black
There are a lot of these WiFi deadbolts available for purchase. I liked the ease of installation, the ease of following the instructions, and the overall operation of the locks. The only time I've had a problem with them was when the batteries got almost completely discharged the first time (6 months after install). I didn't know they were so low because I turned off notifications, duh. Like the title says, these are a good quality, reliable deadbolt at a good price. Love them. ... show more

    • Quality design and unbeatable price!
Color: Black
Review Image by Chris M.
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 don’t 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 don’t 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, it’s not a difficult process—just 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: I’m not a fan of the “hold to confirm” feature for locking the door. It’s 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 you’re 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: I’m really impressed with this Eufy door lock. It’s been a great addition to our home, and I’ll definitely consider purchasing more Eufy products in the future! ... show more

    • Great Smart Lock, but the Touchscreen Didn’t Hold Up
Color: Black
Review Image by Cat Barker
I really liked this keyless entry for my business door. It was nice to have each staff member choose their own passkey and the app let me know who was locking/unlocking the door (if I needed that info). The reason I won’t be buying again, and why I’m replacing it now after 3 years, is the touch pad is all scratched up, which I can’t understand. I think the sun made the screen brittle so even the touch of a finger is causing damage. I’ll be replacing with a button style keyless entry. I don’t think door knobs should need to be replaced frequently but these smart features make it more delicate. Overall it’s a nice piece of equipment. I’ve been really pleased with the whole eufy line. ... show more

    • Bad locks and worse service
Color: Black
I purchased 2 of the C210 models smart locks for my Airbnb property. They worked great at first, and the app is nice but after a few months both units kept draining the batteries. Eufy sent me another set and those were even worse. The batteries drained every week. I can’t have the locks go out with guests staying. I wanted to work something out with Eufy…maybe an upgrade to C220s but a manager, Shane, said that the company doesn’t do upgrades and to return the locks to them and buy other locks. So Eufy wants to lose a customer over $40 (the price difference between C210 and C220 for 2 locks). So my buddy, Shane, emailed me a return label to send all 4 locks back to Eufy. I purchased another brand of locks that manager Shane suggested I do (assuring me in an email that I will receive a 100% refund), had my property manager install them, box up the Eufy locks, and return using the label my buddy, manager Shane, emailed to me. He is now saying that the label is invalid and that I should check with USPS. That is not my problem. It is Eufy’s problem. My PM sent those locks on Nov 14, 2023. I received notifications on my phone on Nov 25, 2023 that the locks had been opened indicating that they arrived at the Eufy facility. My buddy, manager Shane, is refusing to, not only refund my money as I was assured, but also refusing to check with his receiving department. Very poor locks and even worse customer service. If I actually get my refund, I will update my review. UPDATE Dec 6, 2023 My buddy, Shane, is now making excuses about why he will not refund my money despite saying “rest assured” I will get a refund. His stance is that the return label was not activated. Umm…thought it was invalid. Eufy generated and emailed the label to me. Now it’s my fault?? Watch out if you plan to buy a Eufy product which is owned by Anker Innovations. UPDATE Dec 29,2023 I finally received a refund after contacting Anker Innovations directly. It only took 3 months. The Anker rep was apologetic and hoped that this incident wouldn’t affect my feelings about purchasing from Anker/Eufy in the future. My response was that she, (yet another “Debbie” in those companies”) should be more concerned with Shane who could care less about customers or his company and to let me know when Shane was removed from a managerial position then I would change my star rating. Within a couple of days, I received another email from “Debbie” stating that male Shane had been removed but a female “Shane” (she actually used quotation marks) had been placed. Sooo…my ONE star rating remains because I did finally receive my refund, but no more stars for lying and insulting my intelligence. Bizarre folks over there at Anker and Eufy. Good luck to you if you buy their products. I do NOT recommend. ... show more

    • Still working well and looking great 2 years later!

I have had this door lock system for 2 years. Works great! These photos show the finish after all that time, and you can see it still looks really good. My previous (builder grade) door knob was pitted and looking bad in this length of time. Easy install, great instructions, looks good, easy to use app, etc, etc. there is a battery indicator on the app, so you can easily see when it is getting low. It just requires regular AA batteries and I am only now replacing for the first time! If you use the app more, I suppose the battery might drain faster but if I am standing at the door on the inside I just lock it manually out of habit. The convenience of keyless entry is priceless though. The black finish is holding up really well and I have strong sunlight in salt air beating on this door. Great purchase! ... show more

    • **Updated review** works great now!
Color: Black
**Updated Below** Have only had this smart lock for a couple weeks but I'm already having issues. It work perfect for about 3 days then it seemed like the battery died but when I got home I took a battery out then put it back in and it's been fine battery wise. Now, see picture, I can't unlock from my phone at all. It does work from the keypad but I want to be able to unlock remotely, especially because I have contractors working in my home. That is the whole reason I bought this thing. I'll update the review if I figure things out. **Update** I wrote the above review after a week of owning the lock, and I had originally given it two stars. Well I've had the lock for a few months now and I'm glad to say that it is working well I did have to restart it a few times or reset it a few times. A representative from Eufy did reach out to me via email after my original review and gave me some instructions and I was able to fix the lock and haven't had issues since. I've updated the review to five stars because the lock is working great! Thanks Eufy! ... show more
