Excellent replacement for original battery
Excellent replacement for the original battery. With the smart locks on my Disney cabins I need to make sure the batteries are always functional while I’m not there and this really helped. Now my helper just swaps out batteries from fresh charged and they last about 1-2 months between changes.

Battery works as it should and then some.
this battery works great! too bad eufy won't make a few extra battery covers for holding the battery in. such a great lock, why is the cover so cheap with only two plastic tabs on a door that has to open every other day to charge. Oh, well... This was about the battery, not the @eufy The battery charged right up. Not sure how fast, as I didn't need it right away and let it charge until I did. I charged it sveral times before selling the house and had no issue whatsoever with the battery itself.

Doesn't last as long as the genuine Eufy batteries, but nice that it's USB-C instead of micro USB

Good buy. The charge on this battery last as long as on the Eufy one.
I have had this battery for about a year now. The charge lasts around 49 days in the summer and perhaps around 30 days in the winter (-30C sometimes), before I get the notification from the Eufy mobile app that the battery is running low. The charge on the original Eufy battery does not last longer than the Nastima battery so this is a good buy.

Good product, as good as the OEM
This was purchased to keep the door locks working when the OEM battery needed charging. It’s just as good as the OEM, the only difference is the charging indicator. This one uses a single LED that flashes when charging and goes solid “on” when fully charged.
