    • Great Lock for a Great Price

Review Image by Amazon Customer
I bought one for my front and garage doors and I really love them. I was using Yale before and they were ok but the batteries died so quickly and the fit wasn’t very good. I installed these, which were way cheaper and I’m incredibly impressed. I have a few other Eufy products so I thought I’d give these a try and I’m very glad I did. This is the first time I’ve ever installed a lock and it went exactly to plan on both doors with fit and finish. Smart features and fingerprint sensors are also working perfectly. ... show more

I purchased the Eufy Smart lock along with 2 others off of Amazon at the same time. Hands down, the Eufy was the best in craftsmanship and quality. It took about 30min to have it installed. It fits the opening of my other regular deadbolt. It not only makes my condo door look more appealing. It's well made and sturdy and heavy. Setting up the phone app only took about 15min and it's very easy to use. I have had 0 problems with the finger print funtion, one time every time. I love the code support option keypad that my family use. I was able to set up individual codes and even if there not used daily, there haven't been any issues. Even though there is a 2nd knob key lock. I really don't have to use it, because the deadbolt is very tight and secure. The batteries that came with it is still working and shows that the batteries want need to be changed for months. I set it to auto lock and without fail it does everytime. I keypad lighing is great day and night. I don't have to double check it. You can adjust the lock volume. So , I have it loud enough to hear someone coming in, but not alarming. I love the app, because, not only does it notify me that my door is locked when I leave, it alerts me when anyone else does as well. It was more expensive then the other two, however it's well worth the price. As far as installation. If you lay everything out and follow the instructions it's quick and easy. Or you can use Utube. Depending on your bolt hole if you're using the same one, you may have to chisel it out some as the bolt is longer. However, even with doing that it on took 30 min. Initially he didn't and it worked, however chiseling it out with a screwdriver, made it very secure. Money well spent. So impressed my neighbor across from me purchased one. I've been wanting to get one and kept putting it off. This lock has changed my life, with limited use of one hand. I don't have to dig in my purse, I can unlock before getting to the door. After, I enter it locks behind me. I do keep a key on my key ring for back up just in case. Well worth the price. This is a purchase that you want regret. ... show more

    • C220 is the best Eufy smart lock they kffer
Color: Black Item Shape: Modern Set name: Deadbolt
I've tried the higher end palm reading smart lock and it was a complete nightmare. Everybody was either getting locked out or took over 20 minutes to get inside. It then decided to start malfunctioning This one however just works and was easy to set up. Setup was super easy and you can get in quickly It works with all your smart devices and if you already got eufy equipment you are set It has all the needed features the higher end ones have without any of the extra garbage that doesn't work consistently. It's nice to be able to set up temporary codes and fingerprints for people. That would come in handy if you have an air b&b you are renting out and want codes to expire or if you have a cleaning lady or dog sitter. You can remotely unlock the door from your phone at work if the Amazon guy needs to get a package out of sight. I have mine hooked up to my alexas so if I forget to lock one of my doors I can ask her to do it. Highly recommended. Oh, and have a pro locksmith install I it's worth the fee as they'll make sure the unit is installed correctly and the dead bolt has a big enough hole before calibration. ... show more

    • Great lock that makes life easier
Color: Black Item Shape: Modern Set name: Deadbolt
It works well most of the time. I enjoy not having to bring keys and being able to give guests their own access code. It frequently fails to lock in the winter; you have to push the door shut when the inside and outside pressures differ. Maybe it’s my door that is the problem and not the lock. A slightly annoying feature is that it will lock the door even when I just went through it. The timer is based on when it was unlocked and has no idea that you are unloading groceries and will be going through it over and over. Not a deal breaker though. It takes 8 AA batteries, which lasted about 9 months. A rechargeable battery pack would be nicer. Overall, I'm very happy to have it. The installation was simple; it took about 15 minutes. It's really nice not to have to dig out keys or get locked out if you forgot them. ... show more

After doing my research, I settled on the Eufy Smart Door lock to replace our old standard door lock mechanism. The price seemed very good for such robust features. I found it super easy to install and set up. This has been very helpful, particularly for my husband who has forgot his keys on a few occasions. Very pleased with this purchase and would highly recommend! ... show more

    • Eufy’s “Security” System Is a Dangerous Joke. Weak Alarm, Misleading Info, and Useless Support
Color: Black Item Shape: Modern Set name: Deadbolt
I spent over $400 on what I thought was a full Eufy home security setup. I bought the HomeBase 2, the 5-piece sensor kit, smart lock, doorbell camera, outdoor camera, chime, and more. I expected to feel safe in my home. Instead, I got a system that can barely be heard and a support team that doesn’t even understand how their own products work. Only the HomeBase 2 makes a sound when the alarm is triggered. None of the sensors, cameras, or other components ring. Just one small box with a 100 dB siren sitting upstairs next to my router. I live in a two-story home. One day the alarm rang for hours and I didn’t even notice. Neither did my neighbors. What kind of security system is that? When I contacted customer service, I explained everything clearly. I gave them the facts, the issue, and the exact solution. Their replies were insulting. They asked me if I had tried turning up the volume. I had. They told me to try different alarm tones. I had. They told me to move the HomeBase, even though I clearly said it had to stay next to the router. Then they told me to use my doorbell camera as a siren, which is connected to a chime and would go off with every passerby. It’s not even linked to the HomeBase alarms. That suggestion made no sense at all. Then came the most ridiculous part. They actually asked me if my house had walls. Yes, my house has walls. That’s how houses work. If your product can’t be heard through a wall, it’s not fit to be called a security system. It got worse. They asked if my motion sensors and entry sensors made noise. These devices do not emit sound. They never have. It’s shocking that their own support team doesn’t even know how their products function. That’s basic information and they clearly didn’t have it. They also told me Eufy doesn’t make a separate siren. I had to send them a link to their own siren listed on Amazon before they even acknowledged it existed. I asked for two of them to be sent to me as a fair resolution. After dodging the request with emotional reassurances and irrelevant replies, they just stopped responding. To make things even more frustrating, one of the cameras I bought wasn’t compatible with the system. I only found this out through trial and error, because the product description doesn’t mention it. Nowhere does it say it won’t work. That’s on them. There’s no actual customer service number. You’re left emailing support reps who don’t read your messages, don’t know the products, and give you useless copy-paste responses while stalling you into silence. I handed them the solution. I explained the problem from day one. I did all the work for them. The moment I had an airtight case and knocked down every excuse they had, they disappeared. If you want a system that’s reliable, loud, and backed by people who care about your safety, this isn’t it. The design is flawed, the listings are misleading, and the customer service will waste your time until you give up. I regret buying this. You will too. Update: After weeks of trying to work with Eufy support, I was offered a refund that doesn’t even cover the cost of fixing the problem. I asked for two sirens so the system could function properly, or a refund to cover the actual price. They refused both and closed the case. Since I pointed out the siren was on Amazon, it was suddenly removed and now only shows up on their website. I gave them every chance to resolve this and they chose not to. Think twice before trusting this system to protect your home. ... show more

    • Great keyless entry system!
Color: Black Item Shape: Modern Set name: Deadbolt
This is our first experience installing a keyless entry system. The installation was very simple and took no longer than 20 minutes. We just started using it a week ago, and some of the fingers I registered for fingerprint unlock don't work, but I also have quite sweaty hands. I think I may need to re-register some of them. But the codes work flawlessly. It's so convenient not having to take a key out with you. We give our house cleaner a code that is only valid on the days she comes, and it's worked well for us. The app is also very useful in letting you know who is coming in and out of your house. I just hope the battery life is as long as advertised, so we'll see. ... show more
