eufy Smart Lock Touch with Wi-Fi Bridge (Open Box)

Man, what a let down. Some major disadvantages from this unit over the previous one. But one pro - the keys can now be duplicated. The previous model had keys that could not so if you lost one (they used to supply 5), you were out of luck. This updated model includes 2 keys you can then duplicate wherever -- bad thing -- it can't be re-keyed so if using as a rental and you give your key as a backup in case of failure, there's no way to re-key the lock after they leave. The other cons: - Integrated battery "pack" defeats the need to replace AA batteries like before but the bad news is that you can't simply replace the batteries and be done. Instead, you will need to remove the battery pack, charge it, then reinstall. Charging takes several hours. I suppose you could buy additional battery packs but, one step forward, two steps back. - The door lock does not lock automatically very well. I thought it was a defective unit at first so I exchanged it. New unit is the same as before. Previous model would lock well, no issues. This one for whatever reason, doesn't detect the door being closed as good as the previous model. I am constantly having to lock the door manually (in-person) or in app. One time, I didn't pay attention and found the door had been unlocked overnight. Yes, I've tried re-calibrating, resetting, updating firmware, etc. It just doesn't do it well. Maybe a firmware update will address this in the future but this is super concerning. Closing the door behind you and assuming it'll lock automatically is just not a thing anymore (I miss the older version of the lock as it just worked well.). Already contacted Eufy about this and didn't get anywhere. - Battery life is horrible. I do not have a high traffic spot at all and battery drain is bad. Having to recharge the battery so often at this point is just not good. So, stuck with using the keys until this is (hopefully) addressed in a firmware update. I'm researching other locks with better reliability as I just can't justify having this installed and feel comfortable that it's doing what it should. I was such a fan of the older model with the weird keys because it just worked. The AA batteries in those units would drain fast as well which makes me think Eufy just hasn't perfected their devices. That older model worked well for about 2 years and then started eating up the high priced lithium batteries in about a month. At $20+ for a pack of 4 lithium "super" batteries from brand name suppliers and replacing every 4-6 weeks just wasn't feasible. Sadly, I'm returning this and switching to a different brand.
