## Product: eufy FamiLock E34 Smart Lock
**Brand:** eufy Security

## Pros
- Offers a sophisticated palm vein recognition feature that is more reliable and hygienic than traditional fingerprint readers
- Includes a built-in doorbell with 2K video at 180 degrees, providing clear, wide views and eliminating the need for a separate doorbell camera
- No monthly subscription fees due to local storage of video clips
- Solid, heavy build quality with ANSI/BHMA Grade 1 certification for strong security
- Long battery life with the convenience of backup AA battery support during recharging, ensuring continuous operation
- User-friendly app with a clean interface, fast updates, and reliable notifications
- Voice control capabilities add hands-free convenience
- IP65 waterproof rating allows the lock to withstand bad weather conditions
- The palm vein scanner is convenient for users of all ages, including children as young as 9 years old
- Sleek design with a back-lit number pad for easy visibility in bright sunlight and clear doorbell button marking

## Cons
- Palm vein recognition is somewhat slow and can be finicky, especially regarding hand angle, distance, and lighting conditions — often requiring multiple tries
- Performance of biometric scanning drops notably in low light, requiring users to rely on keypad codes after dark or use a phone flashlight, which is inconvenient
- The lock is bulkier and larger than typical smart locks, potentially causing clearance issues with screen doors or narrow frames
- Setup may require router adjustments to 2.4 GHz Wi-Fi networks for stable connectivity, which could be a hassle for some users
- While installation is generally straightforward, some users may prefer professional help due to the lock's size and complexity
- Unlocking speed is slower than some cheaper alternatives, possibly impacting everyday convenience
- The user interface on the lock itself can be confusing initially and may have a learning curve
- The auto-lock feature sometimes triggers unexpectedly, which may require adjustment

## Bottom Line

The eufy FamiLock E34 is a premium, feature-packed smart lock that combines advanced palm vein biometric security, integrated doorbell camera, and voice control—all without monthly fees. It excels in build quality and offers a convenient, hygienic keyless entry solution, especially during daylight hours. However, the biometric scanner's slower performance, especially in low light, and the lock’s bulkier size might be dealbreakers for some. If lighting conditions around your door are limited or you want faster biometric unlocking, you might want to carefully consider these points before buying. Overall, this lock is a well-rounded choice for those wanting an all-in-one security and entry system with local video storage and strong security credentials.

If you need a similar smart lock with potentially faster biometric scanning or less bulk, keep an eye out for alternatives, but for now this eufy model is one of the few with palm vein recognition and integrated camera features.
