Customer Ratings & Reviews

If you want a smart lock with good video, a built‑in chime, and dependable WiFi connectivity—and aren’t super strict about perfection in low light—then the Eufy E330 is a strong choice. I’d recommend it for most homeowners. It’s not perfect, but the pros definitely outweigh the cons

Just installed and it works flawlessly. Took my fingerprint in just a few steps and easily opens the door with it. Nice to have a combo of lock and camera and love that there are numerous options to use- code, fingerprint, app, and key. Also has the option to be able to charge it from the outside if you need to in case it runs out and you forgot the physical key. It's a little pricey, but the build quality is excellent and it was easy to install; so far battery life is good, still at 88% after several weeks and frequent camera checks.

Purchased the Mart Lock E330 with Chime Wifi to allow me the ability to both monitor and allow access to a primary home remodel project and it work perfectly. My IT guy did the installation which took an hour including removing existing deadbolt lock

Great product. A smart lock, video camera, and doorbell all in one. Video clarity is better than what I expected. Surprisingly, it shows more than I expected too. It was easy to install and connect to my Google home. I watched a lot of reviews on smart locks and doorbells with cameras and this one is what I chose to go with and I don't regret it all. The rechargeable battery lasts a long time and is easy to recharge. My other locks use AA batteries and I just hate the waste.

Very good smart lock, all in one. The battery lasts forever no complaints at all. Very easy to install and app works really well, I bought 3 (three) for my condominiums.

Eufy Video Doorbell S330 is a Frustrating and Unreliable Smart Home Device After extensive research, here's a scathing review highlighting the numerous shortcomings of the Eufy Video Doorbell S330: Installation Nightmare The setup process is an absolute nightmare. Installation takes over an hour and requires drilling into your wall, with a complicated process involving a HomeBase 2 that must be connected via ethernet cable5. The devices loudly blare unnecessary instructions during setup, adding to the mounting frustration5. Performance Issues The doorbell suffers from critical performance problems: Extremely slow motion detection and notifications3 Poor night vision that becomes essentially useless beyond 10 feet3 Frequent issues with motion tracking, often missing or late-triggering events1 Technical Limitations The camera cannot be easily adjusted, leading to awkward viewing angles4 Large and bulky design (almost 16cm in height)5 Unreliable motion detection that frequently misses events13 Software Concerns The Eufy app is plagued with bugs, creating additional frustration for users. The "View Event / Live View" bug is particularly annoying and affects multiple Eufy products4. Key Drawbacks Inconsistent motion detection Poor night vision performance Complicated installation Oversized design Buggy mobile application While the doorbell offers some interesting features like dual cameras and free video storage, these are overshadowed by its significant reliability issues. Save yourself the headache and look elsewhere for a smart doorbell solution.

Work perfectly. Easy to install. Specially for family uses strongly recommended

The product is a little pricey at first but in the long run it’s worth it. You will have to buy an SD card in addition to the lock. Before I installed the lock I charged the battery that came with the product. The install was easy and then to get it connected with the app was also pretty easy. I’ve had it for a couple of months now and still have recharged the battery and haven’t had any issues.

Needed controlled access to a door with logs to track. This was the perfect lock that did the trick! But wait, there's more! I can restrict by time and person. Also have video of who enters and exits when the lock the door again. Great lock and great buy!

so much better nest product. easy to install and love the rechargeable battery.

Eufy's no contract necessary system is incredible with the best detection and greatest ease of use over any system I've tried in years. This unit is great with an extra wide view and perfect picture quality to see things clearly. The chime is loud enough and haven't had a fingerprint mis-read yet. Pairing was simple too.

Excellent Product, I am so happy, I already installed and seem works everything well

I like that this has the doorbell, camera, biometric reader, code, and hidden key all included. The camera looks great.

Nice little set here recommend to people looking for cam

Easy installation and great picture quality. I wish there was a way to adjust the recording length for events, so it would record for a length of time after, but overall great purchase. I like that I can view the live stream and unlock from anywhere, or generate temporary passcodes for limited duration or one time use.

It has a signifigant delay in the microphone to audio but otherwise the picture is clear, great night vision. I wish i could get better alerts on my smart watch, like a photo of the human alert. The only thing the watch is good for regarding the lock is it can lock / unlock remotely

Love our new eufy e330. We can see who goes in and out and all the features it comes with. The installation was a little frustrating because you aren’t suppose to have it over tightened but all in all it’s been a great lock for my family and I

The eufy smartlock and doorbell work well. I also like that I do not have to pay a monthly subscription to use the app.

It made the life way easier not having to look for my keys since I always come home with something in my hands. The problem with it is that the touch will fail 3 out of 5. The camera doesn’t capture some of the events especially if they happen quickly. For each event, it gives me at least 2 notifications which is really annoying. The battery is very good but when it’s almost empty, it takes 4 hours to recharge. For this one, you need to have a spare battery specially, if there is going to be too many triggers. It has some settings that you can reduce triggering the camera but they work only if you have enough space between the object and the camera. They don’t work for me because I don’t have that space/distance.

I was able to replace my old lock easily. Everything works smoothly. I was impressed with the battery. On optimal battery mode, I'm using less than 1% battery per day in a household of 5 people.
