Do not buy
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It's not the best lock specifically for the price, I've had mine for going on 4 moths and it has recently been ringing the doorbell for no reason at all hours night and day. Pretty freaking annoying! And the thumb turn after certain amount of time specially over night it gets hard to turn, you literally have to force it open! I'm sure that will start wearing down the whole thing. And don't try and send feedback to the company because you will get some lame automated response that doesn't have any useful information!! Overall I'm extremely disappointed with this product and I have several of their cameras both indoor and outdoor, but after seeing the quality of products they are selling now I won't be buying anymore Anker products at all. Don't waste your $ on this crappy product it's over priced and disposable its an expensive mistake.

Does not stay connected to Wi-Fi
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Very dissatisfied with both this product and customer service at Eufy. This smart lock does not stay connected to the Wi-Fi for more than a day. Then you have to be near it to manually reconnect it again. After doing some research, it seems to be a known bug. Hundreds of people have been experiencing the same thing for over a year and Eufy has not fixed it. I will be returning. We bought this item for the Wi-Fi capabilities and it let us down.

Super happy with this lock
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The lock is AMAZING. I had it installed by BestBuy as well and I’m super happy with it. Everything works well and the features are super practical (especially the fingerprint scanner). Note that you’ll need a passage lever given this is only the lock/ deadbolt.

It’s so great I bought 3 for my beach house. I’ve had august smart locks which have been awesome but this eufy is a game changer. It’s easy, simple, and smart especially the finger scanner.

This Is The Best Made Lock I've Ever Had!!!!
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.When I first received the box and opened it, I was immediately impressed by the high quality metal that the lock was made of. I then went to my door to switch out everything and ran into a few stumbling blocks, like when I put everything together screws and all, the plug came out on the inside, so I had to take everything apart, plug it back up, and screw everything back in again. Then I realized that the battery pack needed to be charged, so I had to go plug that in and charge it. Then I was having a few issues with the app, which I had to uninstall and install a few different times. At least setup was a breeze as long as you follow the step-by-step instructions and not try to skip anything. Another thing that I didn't like, was how hard it is to get the battery cover off and on of the lock itself. After everything was hooked up and ready to go, Iike programming the lock with my phone, inputting my code and fingerprint, which was pretty easy and effortless. I begin testing it out and making sure everything worked. There were no issues when scanning my fingerprint, adding the code, using the app to lock and unlock the door, and pushing the button to lock the door from the outside. What I don't like, is the fact that when you lock the door from the outside, you have to hold the lock button for a few seconds. It would be nice if you could just push it once and it locks. I would also like to input more than one code for different people. Other than that, this lock set is phenomenal! I don't ever recall thinking this about a product before, but I think this one is underpriced for everything you get! The Wi-Fi is a big plus, to lock and unlock your door from anywhere for anyone. I also love the notifications of when the doors unlocked and locked. I also sent my daughter a link so she can have the same type of access I have, and she loves it! She especially likes the fact that when she has a lot of grocery bags in her hand, she doesn't have to fumble with the key to unlock the door, she can just unlock the door with the app before she even gets out the car. I also like the really cool feature, of how the door can automatically lock, if you set it, when it's closed. There has been a few different times when my daughter and myself has forgotten to lock the door. This is a must-have for anyone who appreciate quality and well made products!

Good smart lock
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Really nice lock works well. Notifies you if there is any issues with the lick getting stuck or the door being left open. Only issue i have is the auto lock feature is a tad goofy it always locks after 3 minutes but when you change the length of time for the lock it does not always activate whej you have it set to do so

Terrific deadbolt
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I love how I can just use a finger print, a special code, an actual key, do a temporary code for others and be able to see the activity of whom has been in and out of my home. I would buy it again without a doubt. I'm thinking of buy one for a family member as a Christmas gift.

The Smartest Smart Lock Available
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I have used numerous smart home devices over the last few years including three different brands of smart locks. Each had their strengths and weaknesses so I was curious to see what the new Eufy Smart Lock Touch & Wi-Fi had to offer. Upon receiving the box its weight alone was impressive and surprising. The actual lock is well made and has a high quality feel and look. The parts are made of drill proof and magnet proof steel. Unboxing revealed a plethora of parts and boxes. I was initially thought this installation appeared like it may be confusing and laborious. Not so. This feeling faded quickly as each box is clearly labeled with what step of the installation process the parts are needed for. The included installation manual is very simple to follow and is quite detailed. The manual first instructs you to download the Eufy security app to your mobile device. You’ll need it later during the installation. I jumped right in with the first step being the removal of your existing lock. Please note that the only tool required for installation is a screwdriver. This took moments but you sure sense at that point that there’s no turning back. Following the instructions I next installed the included deadbolt. You’re then ready to the begin the Eufy hardware installation. You start with the exterior assembly. The exterior assembly is the part with the fingerprint reader and keypad. You then attach the interior mounting plate to the inside of your door. The mounting plate attaches using screws that pass through the existing hole in your door. You next thread a cable from the exterior assembly through the mounting plate to the interior assembly. The cable only attaches one way so you can’t mess it up. You next simply attach the interior assembly to the mounting plate using a few screws. The interior assembly is the inside part of the lock with the battery compartment and the thumb toggle to lock the door. You next install the included 10,000 mAh rechargeable battery and then the Eufy came to life. This completed the extent of the actual hardware installation. What a breeze. The entire installation may have taken me 15 minutes. At this point you move on to the setup part of the installation. Here you now need the Eufy security app. Using the app you simply select add a device in the app and select the Eufy Smart Lock Touch & Wi-Fi. You’re prompted to scan a QR code located on the interior assembly. Next you push the setup button below the battery pack and you’re ready to connect the Eufy to your WiFi network. Upon completion you can calibrate the locking function and then setup an access code and register your fingerprint so you can unlock your door with either the code using the keypad or by scanning your fingerprint. This is pretty much the extent of the setup process and you’re ready to use the lock. I did notice within the app that there was a firmware update available which quickly installed. I immediately wanted to test how well the Eufy Smart Lock Touch & Wi-Fi worked. I started with the fingerprint reader. I was immediately impressed with it accuracy, speed, and its quiet operation. You can add several fingerprints if you like. This sure comes in handy so you are set to scan either hand if one hand is full. I love the fact that there are 6 ways to unlock your door including using your phone with WiFi or Bluetooth, using your passcode entered on the keypad, using the fingerprint reader, using an included physical key, 5 are included, or by using Google or Alexa voice assistant. Additionally the same 6 options also lock the door. There is also an auto lock feature that will detect when you close your door and will lock it automatically after a delay that you set in the app from 1 second to 3 minutes. A great feature so you never forget to lock your door. I quickly found the fingerprint locking and unlocking to be easiest method for me but I’m sure I will use the other methods depending on circumstances. It’s great to have all these options. Other smart locks I’ve owned were not this smart! In fact one great advantage the Eufy has is that it uses WiFi. My other locks were Bluetooth only and that made them much more limited in functionality. With WiFi you can lock or unlock your door from anywhere and you get instant notifications anytime your door is locked or unlocked. You can also check a list of lock events that show you when the Eufy is locked or unlocked and by which user. That’s right you can add users, assign passcodes or register their fingerprints. That way every family member can have their own access. Great way to monitor when the kids are coming and going. Another fantastic feature is the ability to add guest access. I imagine this coming in handy when having family or friends visit. You give them access within the app and they will receive an email notification to install the app and gain access to your Eufy. No need to worry about handing out keys or having to be present to let a house guest into your home. I own other Eufy smart home products and the Eufy Smart Lock Touch & Wi-Fi is a great addition. This smart lock is by far the smartest and most full featured smart lock I’ve owned. The design is attractive and the build quality is fantastic. The Eufy is in fact rated to last 30 years. Now that is a well made product. I have zero complaints about this product. Highly recommended.

Have to charge battery every couple weeks
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Seems like it would be a nice lock. My problem is once a week I have to charge the battery that is supposed to last a year. I’ve tried to find another battery to no avail. I have emailed back and forth with support and not accomplished anything. So wanted to like this. Thought my August went through batteries.

Bad app intergration
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Easy to install, features worked fine. But the app refused to unlock the door remotely and without the app you can't add even add other profiles for finger prints and key codes. Uninstalled rebooted, would work for a little but then reverted back to an nonworking condition. Shame,really loved it at first.

Works when it wants to.
||Posted . Owned for 1.5 years when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Buy a different brand, this one isn't really worth the headache. Makes a grinding noise, turning the deadbolt from inside isn't smooth and the mechanism gets caught. Constant DOOR FAILED TO UNLOCK errors. Lousy one year warranty that just expired.

Normally, a little twist in the opposite direction will restore the lock and you can continue to open and lock it. Could you please have a try?
