this is really convenient, i love it. first of all, the ability to unlock and lock from afar is sooo good. as is the choice to be notified when the door has been successfully auto-locked, since my mom tends to be paranoid about that. and it's crazy customizable! you can even customize which part of the screen needs to see movement to trigger an alarm, and how far the camera will sense in different radians of the screen (im explaining that badly, but it's basically like--you can assign the left side of the camera's screen to sense movement up to 6 feet away, but in the middle of the screen, have it sense up to 15 feet away) i never had such a smart lock before, so maybe this is normal, but anyway i was dead impressed. the fingerprint scanner isn't always consistent, but that's just the manner of fingerprint scanners, even the ones on your phone... not a biggy as long as you record a few different fingers, since it'll read at least one if not the other. the company seems very attentive to its customers, according to what i saw online. when i emailed them, they also sent me the round deadbolt holder (? brace? faceplate? what do u even call that) to replace the rectangular faceplate. (granted, they did forget about me bit and i had to remind them a week later, but i found it HILARIOUS when they sent me what was basically the professional version of an "oh shit, oh shit, sorry" email, so im not troubled about it.) i do wish the notifications or doorbell sounds from the machine can be adjusted in volume separate from the other volume controls, but maybe it'll be a future addition :)

    I¡¯ve been using this smart door lock with a built-in doorbell for a few weeks now, and it¡¯s been a game-changer for home security and convenience. The installation was relatively easy with the help of the step-by-step app instructions, and the lock integrates smoothly with my smart home system. I love the ability to lock and unlock the door remotely, grant temporary access to guests, and receive instant notifications when someone rings the doorbell or enters. The camera quality is sharp, even at night, and the two-way audio is clear for communicating with visitors. Battery life has been solid so far, and the build quality feels sturdy and premium. Overall, it¡¯s a feature-packed, reliable upgrade that adds both peace of mind and modern functionality to the front door.

    The Eufy Security Video Smart Lock E330 is hands-down one of the best smart home purchases I¡¯ve made. The 3-in-1 functionality¡ªdoorbell, camera, and fingerprint lock¡ªworks flawlessly and has made coming and going so much easier. The fingerprint reader is fast and accurate, and I love that I can remotely unlock the door through the app if someone needs to get in while I¡¯m away.

    The built-in camera and doorbell are super clear, even at night, and the motion alerts are prompt without being annoying. Setup was surprisingly easy too¡ªno wiring nightmares or professional help needed.

    It auto-locks behind me, which gives great peace of mind, and the app is user-friendly with all the features you¡¯d expect (and a few I didn¡¯t know I needed).

    Highly recommend this for anyone wanting a secure, smart, and convenient upgrade to their front door.

    If I could give this a 4.5 out of 5 stars, I would. Functions as intended; however, the battery life is to be desired. The battery seems to last 2-3 months with the default settings. I guess other factors, such as constant activation by neighbors, might play a role; however, the battery size is a decent size battery. I expected around 6 months minimum. Other than that complaint, this has been a great addition to the property. Videos are clear, the doorbell can be heard, and the unlock/lock feature works as intended. The build quality of the device is great (not plastic-y), and the assembly was simple. If needed, there are YouTube videos for setup, and the app assists you with the setup.

    Update to my experience:

    So originally I gave this particular product 3 Stars because I'm not a fan of the E330's lack of a door sensor which would not allow the door to disengage the auto lock when the door was wide open. For example, someone goes out to take care of the trash, leaves the door open for a few seconds, dumps the trash and returns to the door to find the deadbolt engaged and the door open.

    Apparently Eufy (Anker) saw my original review and reached out to me regarding my statements about their product. Again, I was told that the E330 doesn't have the door sensor but the S330 does. I told them that information is not clearly visible on the product page for the E330 and that with the knowledge that the S330 had the door sensor, it really makes the E330 irrelevant and should not be a mainstay on the market. Both the E330 and the S330 have the same functions and features save for that door sensor as well as the S33 coming with it's own chime which just so happens to have an expansion slot on it for memory storage of the product videos.
    Eufy did the unthinkable and offered to replace my previously purchased E330 with an S330 and I was elated. They asked me what I was looking for in a smart lock and I told them just what I had said in my review: the E330 was ALMOST perfect, but the lack of a door sensor left me with a little bit of buyers remorse as it, at least to me, is a crucial feature for a "smart" device that's primary function is to provide a variety of ways to lock and unlock a door in person or remotely.
    Eufy offered to send me an S330 to try it out and they did make a disclaimer, stating that essentially the lock does have a door sensor on it, but it does have a timer that will still engage the lock after a set time whether the door is open or not. At first this seemed sort of counter-intuitive, but I said I will give it a try anyway. They immediately shipped me the new S330 and I received it just a couple days later.
    Let me say this, the S330 is noticeably heavier than the E330 and I thought that was a good sign. The two models are very similar in appearance with both being advertised as a 3-in-1 Camera, Doorbell, and of course a lock. Both sport a 2K camera that is sharp and detailed with great video capture capabilities. Both can be tied to your in-home WiFi and accessed remotely. Both have excellent fingerprint readers, although I will say the S330 one is physically more robust and it also is slightly more accurate in the way of consistency. Battery life between both are pretty much the same. The more features you have turned on the more battery is used so the battery goes fairly quick if you have everything on. Based on my current rate of battery usage I am expecting maybe 3 months of battery usage between charges. Your mileage may vary as we have lots of kids and therefore lots of activity making use of the camera be it passage through the door or little ones playing on the porch. Yes, there are settings in the app for this and I will speak about that shortly.
    Both products have a keyhole hidden behind the button that functions as a doorbell. Just pull the button out some and allow it to pivot to expose the keyhole. Both products come with two keys which brings the number of usable ways of unlock and entry to 4: the fingerprint reader, the physical key, the keypad, and the app. The keypad is great and allows me to program a code for each of my family members (as well as their fingerprints) into the unit. Additionally, you get a notification on your phone when programmed members use their code or fingerprint to enter the door. You can set each member to have constant access or temporary access via these methods.
    As stated previously, the S330 comes with it's own chime which in this case is like a programmable doorbell. It is something that you simply plug into an outlet and it carries 2 additional functions to it being a doorbell: 1) It acts as a hub/extender for the door lock. So if your router is a little further away from the door you can place the chime somewhere between the router and smart lock to gain a better signal, 2) this is where you can install an up to 128GB micro SD card for video storage, which is great if you want to store your videos locally and not have to pay a subscription.
    The door sensor in the S330 works great. Previously with the E330 the deadbolt would slide out with the door wide open after so many SECONDS. The only alternatives to this is to either set a schedule for a time of the day when the auto locking feature is not used or simply turn it off all together which completely defeats the point of having a "Smart" lock, in my humble opinion. Now, with the S330 the lock does in fact stay unlocked until you close the door, then the deadbolt slides into place. The disclaimer that was mentioned before had to do with the door still auto locking after 3 MINUTES time, whether the door is open or closed. I've now come to believe this is a fail safe for when the sensor may have miss the closed door event that would normally trigger the auto locking function immediately. In the case of a missed event then it would make sense to engage the lock after a set time "just in case". Either way you look at it, the lock now functions the way it's suppose to and locks and unlocks at reasonable times.
    Just a side note, the chime does allow for some pretty cool doorbell sounds that you can choose in the app. Speaking of the app it's very well thought out and intuitive with a robust set of features that allow you to customize your experience with the device in every practical way. Getting it on WiFi is a breeze and integrating it with Alexa is easy with the Eufy skill enabled.
    My only recommendations to potential buyers is 1) Try and wait for a sale on the products, whether you aim for the E330 or S330. These things are pricey and although I find that it is very useful and highly convenient, especially for larger families like mine, it is definitely a sizable investment for something that amounts to a security camera on steroids. On the other hand, it's a security camera on steroids! It allows you to monitor who enters your home or even approaches your home from afar be it your bedroom or a hotel room 1000 miles away. Number 2) Get an additional battery. Again your mileage may vary, but I've come to find that the 10000mAh battery that comes with these devices last a decent amount of time but takes a decent amount of time to charge. So, with that being said, it makes sense to have an extra battery on hand to charge while the other one is in use, set it aside until it's time to swap them out, end then go on your merry way.
    Both are fantastic smart locks, however the S330 is just far more practical to me. I highly recommend these products and I have to say Eufy customer service is out of this world. They have done a great job communicating with me and I feel they have been straight forward with me regarding their products. Also, I want to say I was the one that offered to rewrite the review IF the S330 met my needs and expectations, which it most certainly has. I rate the S330 5 stars, hands down. It checked all the boxes and looks great while doing it. My reasoning for my original 3 star rating for the E330 is mentioned below in the original review:

    ****
    This would be perfect had it not been for the absence of a door ajar feature. As some have said the E330 does not have this feature and the S330 does. For those who don't know, this feature is what tells the lock to not engage the auto lock feature until the door is closed. Without this feature the E330 is not smart enough to know that the door is open, so it just turns the deadbolt with the door wide open. The solution per the company is to turn the auto locking feature off which definitely defeats the purpose of having a "smart" lock.
    For the price one would think a feature like this would come standard, but I digress.
    Every other feature about this smart lock is very good and the quality is outstanding. The battery charge? Not long; a few months maybe. But then again I have kids going in and out all the time.
