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

I've had two WiFi Locks by well known companies that failed within the first year and they wouldn't replace their locks as they both only had a 90 day warranty. That made me start looking for a replacement and that's how I came upon Eufy. I read reviews and found that they have a very good reputation. So I decided to plunge and buy. The other two companies required this extensive process for installation. Eufy's installation was so easy it wasn't funny. I set aside an hour to install figuring it might take longer but my installation took less than 30 minutes. I was astounded and integrating with Alexa was a breeze. It literally took a few minutes. All I needed to do was to download the skill and Alexa did the rest. I love being able to check the status of my lock from the Alexa app. And I get notifications if I leave the house and have left the front door unlocked. The other thing I love - I added locking the front door to my evening routine. I tell Alexa Good Night and the living room lights are turned off, Alexa checks to make sure the front door is locked and then my bedroom light is turned off. You gotta love technology!! You want to buy a simple but efficient and reliable lock that works with Alexa, then this is your product. Just make sure that you order the Eufy WiFi Lock that works with Alexa. Well worth the budget price! ... show more

    • EXTRAORDINARY
Color: Black
I replaced a Yale lock that I could not connect to remotely. The lock has a separate plug into an outlet that facilitates connecting to Wi-Fi. Never work from the beginning The keypad worked but not having access, defeated the whole purpose The only reason I bought EUFY was the price. For under $100 it beats the Yale and the Schlag locks by $150 or more It is package beautifully. The instructions are simple and clear. And it was very easy to install. It was extraordinarily easy. It connected to Wi-Fi without a glitch I’m going to buy another one for the door opposite this. And then when I get back to our other home, I’m going to get one for our front door and replace the Yale lock. The yale like has to connect through wink. After I had it for about two years wink decided to start charging me five dollars a month. EUFY is a no-brainer. And now I’m going to look into more of their products. ... show more

    • Pretty good lock! Helps notify us on who is entering our home! Convenient!
Color: Black
I recently upgraded my home security with the Eufy Security C210 WiFi Smart Lock, and I must say it has exceeded my expectations in every aspect. This intelligent device seamlessly combines advanced security features with unmatched convenience, making it a standout addition to my smart home. I really like that I can create multiple passcodes for entry into my home. This makes it easy to be notified on who is entering the home, such as HOA or cleaners etc. The setup process was incredibly straightforward, and the integration with the Eufy Security app was seamless. Within minutes, I had the C210 Smart Lock up and running, allowing me to control and monitor my door from the convenience of my smartphone. The user-friendly interface of the app adds an extra layer of simplicity to managing my home's security. Security is, of course, a top priority, and the Eufy C210 does not disappoint. The robust construction and advanced encryption protocols provide a sense of confidence in the protection of my home. The tamper-resistant design and anti-peep technology ensure that unauthorized access attempts are thwarted, adding an extra layer of security to my front door. I only had one incident that created hesitation. In the middle of the night we heard the lock. It sounded like someone was trying to break in, however it was just a low battery or the wifi had gone out. Other than that, I would highly recommend. ... 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

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

    • Eufy smart lock
Color: Black
I have never used the Eufy brand of electronics before so I was a bit hesitant to spend the money but what one me over was the that this lock in particular does not require drilling and extra hole into the door for the mounting plate (Its optional) and it's still sturdy with well attached without those extra screws. The installation process was very easy and took less than 30 minutes. The instructions are clear and concise. Appearance wise this is a very sleek but smart lock. The digits pad is simple but modern and simple looking. Even my matienance man was able to use it without instructions. Connecting it to the eufy app was hassel free abd simple as well. It did lose connectivity once in the early days but since then I've had no issues. The lock does have auto lock feature and you can set individual door codes for people. All of this has to be done in the app. Overall I love this door lock and the brand did not disappoint. Im actually looking at getting their smart lock/camera/doorbell device for my front door. ... show more
