This Tapo at Walmart for $49 is a good alternative and arguably better with the Tapo app.

About 3 months. But I usually charge it when I see it down to 1 bar. Vs waiting for it to say battery low. Cuz I lost the key haha I'm scared that it'll die and I'll be locked out

Have the c30 deadbolt only and it never stays connected, making the core functionality worthless. I tried setting up a static IP so I'm waiting to see if that helps. Also battery life is way worse than the much older fingerprint one I have from them. 1-3 months vs maybe a year, AND the fingerprint gets used twice a day vs almost never using the battery on the c30. Anker support won't talk to you without first providing receipts and stuff which was another hassle on top of my busy day when they could have just looked into my account (same email I contacted them from). After this and a couple other duds I'm done with the eufy smart home ecosystem.
Edit: and it's already dropped off my account again.

I have the E330. The camera and doorbell works great. The only issue I have is with the deadbolt. Sometimes it gets jammed and does not open/lock properly.

Good lock for the price, if primary entrance would spend a little more for better battery life.

This is a cloud-based solution. It does not appear to have a local workaround. Good choice if you trust Eufy with the keys to your house and the term of their support before bricking this (or adding a subscription model).

Seems to be BHMA Grade 3. I'm thinking I'd prefer something more rugged/secure.
