Review: Impressive and great features - Impressed with all the options and features. UI Is a bit confusing tho and I do agree that the hands/vein technology is difficult to get to work. I’m gonna try creating multiple versions of my hands to see if that’ll improve things like I’ve done with the thumbprint one. Actually wishing I had the fingerprint one still. The video mechanism works great and you can choose different lengths to film, which I really like. I did feel that the battery could’ve lasted a bit longer. It lasted about a month before it needed recharging them but the four AA batteries held fine while it was being charged. This was with a lot of people coming in and out though. Np installing to door (although had my handyman do it). NOTE: after putting it together it will have u press a button in the back wheee the battery is and if u already put the cover on np bc it’s super easy to take off. I did have to try connecting a couple of times. If you have issues with this part and it talks about router settings go to your Internet provider settings online or app and change signal to 2.4 only from dual band (2.4 and 5.0) temporarily and then u won’t have a problem.
Review: Great all-in-one security, but the palm reader is a bit picky - I bought this to replace a separate doorbell and lock, and it definitely cleans up the front porch. The 2K video is sharp, and I love that there’s no monthly subscription fee to see my clips. Installation was straightforward and took about 30 minutes with a standard screwdriver. Pros: • No Subscriptions Huge win. Local storage is the main reason I went with Eufy. • Camera View. The 180-degree lens actually lets me see packages sitting on the ground. • Build: The lock feels heavy and secure—doesn't feel like cheap plastic. Cons: • The Palm Reader: This is the headline feature, but it’s not perfect. It works about 85% of the time on the first try. If your hand is at a slight angle or if you’re standing too close, it usually fails and you have to reset and try again. It’s still faster than keys, but not as "instant" as I hoped. • Bulk: It’s a very large unit. If you have a screen door, double-check your clearances because this sticks out quite a bit. It’s a solid upgrade if you want to ditch your keys and your doorbell subscription in one go. Just be prepared to have a little patience with the palm sensor until you learn exactly where it likes your hand to be. Battery life is long

### ⭐⭐⭐⭐⭐ LOVE IT! Great Upgrade from our Fingerprint Smart Lock!
*by N***S on August 9, 2025*

Replaced our fingerprint-reducing Eufy smart lock. I LOVE the palm reading feature (so much easier, and more reliable than the fingerprint reader, which was causing me grief after 2 years, as it kept failing to recognize my fingerprints). But this new smart lock is amazing, and the palm reading feature seems to work without any problems (knock on wood). Things that I especially like about this: 1. No need to touch the lock (like with the fingerprint reader) 2. The Black color looks much sleeker than the old silver-toned lock we had…PLUS, the black color makes reading the back-lit number pad SO much easier to read (our old lock was silver, with white numbers, and even being back-lit, it was next to impossible to see the numbers, especially in bright sunlight). 3. Love the locks integrated camera & doorbell (allowing us to remove our separate Eufy doorbell camera, which was starting to get annoying in terms of needing to charge it every 6 weeks or so). 4. The doorbell button is easy to recognize - it lights up and has a small bell icon on it (believe it or not, with the basic Eufy doorbell camera, the design is such that the camera lens and the doorbell button are both about the same size and shape, and the button wasn’t marked or labeled — and I can’t tell you how MANY times people came to our door, thought they were ringing the doorbell, but were really smashing their thumb onto the round camera lens! — mademfor funny videos, but not a very effective doorbell if people don’t know where to press) 5. A HUGE added benefit of this model is the long battery life, PLUS the back-up AA batteries that function if the main battery dies (unlikely if you’re paying the slightest attention to your Eufy app)…but more importantly, the AA batteries work while the main battery is being re-charged (so you don’t have to leave your door unlocked all day, like we had to do with the old Eufy lock, because we needed to be able to have people come and go). Overall, I truly LOVE this smart lock, and I expect to get many years of enjoyable use out of it (again, knock on wood!)
