Good software, easy to install, value for money.
I use this one for all my units. And it's really good. For those who expirince often disconnect ussues. It cause your wifi router is bad. It works perfectly on 2.4 GHz network channel 1. If you router starts messing with frequencies or jumping on channels, the connection will be lost. Other than that no issues at all. Works very stable, doesn't drain battery. Honestly, nothing to complain about. And app is quite good. It's reliable and always works.

Great item
Easy to install if your door having universal holes Very convenient and the application is very user friendly Little issues but you can live with it - auto lock doesn’t distinguish between open or closed door so lock can be activated while door is opened and you need to unlock it manually - you can’t set up password without internet near to the door

Frustrating to say the least
I have been using this device for about 6 months now. My biggest frustration is that it disconnects to the wifi and you then wouldnt know who’s accessing your home (because I’ve given multiple people different passwords). Reconnecting takes up to 2 hours. I’m not satisfied at all

idea is good but not suitable for rented homes
item is good to have but you have to make a big hole in main door to fit it, if you are in rented apartment , landlord might ask more money when you move out

This lock is advertised as capable of locking/unlocking via BT. This is not true. The customer service I contacted claimed application unlocking is what is meant by BT but it is not BT, it is wifi unlocking and clearly needs a connection to the company server. In other words, one has to be connected to the internet to unlock it from within application. After I stated this simply fact the agent got disconnected.

Like this, had it a few months now and like the way it works and sends notifications when door is locked and unlocked.

Me encanto, súper fácil de poner si tienes la herramienta adecuada, lo único que no me gusto es que no se puede abrir o cerrar por medio de ubicación aunque eso ya es del software de EUfy pero la calidad es muy buena y funcional para todo lo demás. Sería Perfecto si fuera compatible con apple HomeKit y con ubicación

This is a great smart locker. The built in wifi feature is the best compared with the other smart locker that need a gateway to connect to the internet. The installation is straight forward and the app works perfect. The quality and terminations of this product is at the same level of any other more expensive brand. I have seen some reviews talking about the short life of the batteries. I will see how much my batteries last. However, I have found some good 3300mWh AA batteries from Amazon that could solve this problem, if that were the case. I think, eufy should add the power consumption in the product specs. That way would be easier to get the batteries that best last for this locker. The only thing I am missing from this product is the Auto Unlock feature they have in the cheaper version. For the price of this product, it should have all the features their brand offers. I hope they will add it and we can get it just by updating the software. One more recommendation is to improve the one tap locking. You have to touch the ok button for 3 seconds or more. Maybe by touching 0-ok could be faster. With the cheapest version this feature works better. It is just a press key and it lock right away. In general, this is a great smart locker. It just need some improvement that can be done in the software, so actual customer can enjoy it.

There are a lot of these WiFi deadbolts available for purchase. I liked the ease of installation, the ease of following the instructions, and the overall operation of the locks. The only time I've had a problem with them was when the batteries got almost completely discharged the first time (6 months after install). I didn't know they were so low because I turned off notifications, duh. Like the title says, these are a good quality, reliable deadbolt at a good price. Love them.
