Prime Day 2025 is here from Tuesday, July 8 to Friday, July 11, and Lifehacker is sharing the best sales based on product reviews, comparisons, and price-tracking tools. 

The Eufy Video Smart Lock E330 tries to do a lot, and surprisingly, it does most of it well. Now down to $189.98 for Prime Day (from its usual $299.99), this hybrid device is part doorbell, part security camera, and part keyless lock. The fingerprint scanner, camera, touchpad, and doorbell are all built into a single, clean-looking panel. Even the keyhole is hidden behind the doorbell button. It’s the kind of gadget that sounds gimmicky until you realize how seamlessly it blends into daily life. PCMag even called it the best smart lock of 2023, praising both its versatility and strong performance.

What makes the E330 stand out is how many ways it gives you to get inside your house. You can unlock your door using a fingerprint, PIN code, the app, your voice via Alexa or Google Assistant, or just a regular key. As for the video quality, its built-in 2K camera is sharp enough to recognize faces, and the dual motion sensors (PIR and radar) do a solid job of telling people apart from passing cars, notes this PCMag review. Video is stored locally with 8GB of onboard memory, but it also works with Eufy’s HomeBase 3, which lets you expand storage up to a whopping 16TB if needed. And since it comes with IP65 weather resistance, you don’t need to worry about dust or rain messing with its electronics. The battery is rechargeable and should last around four months between charges, depending on usage. And while the E330 doesn’t support Apple HomeKit or IFTTT, it makes up for that with solid performance and a simple app that lets you control everything from access codes to motion alerts.
