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!

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.

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.

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.

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.
