Had no problems connecting, never set up one before but it was simple.

Mine did not come with an exit button. That's not legal! There is no way for somebody to get out in case of an emergency, like a fire. Yes, you could use your app to unlock the door to get out, but if it's in a room there needs to be a way out in a hurry without the app! Unfortunately I had mine all hooked up until I realized there was no button. So now I put holes in my office’s door and hooked this all up for nothing.

This lock holds a door closed very well. It is very strong and makes a great lock.Hardware installation is super simple. It took me about 30 minutes to install the hardware part of this lock.Interfacing with my smart assistants was also very straight forward and did not require any great effort. I can unlock the door with my voice whenever I want. This feature should only be used where someone who is at the door can't yell loud enough to the smart assistant inside that it defeats the lock.Getting the tags and cards to work is a real nightmare. The instructions for getting the cards and tags to work are really bad. There are no third party Youtube videos that I could find for help. I did eventually figure out what they were telling me to do, but it is a complex and confusing method. Be prepared to be amazed at the complexity and poor instructions.Once installed, this makes an excellent and flexible door locking system. I can give out tags and cards to authorized individuals so they can enter without assistance. I can disable lost tags/cards. I can allow access with my voice to the building when I need to. I can setup timers when the door is locked and when it is not. The keypad has a door bell button allowing me to be alerted when someone wants access. The door automatically re-locks once someone has been granted access.This is a very nice door locking system. I would give it 5 stars if the instructions were easier to understand. As it is, I give it 4 stars!

Not for the average DIY'er. The installation and programming of this magnetic door lock and access control is going to take some time and require some patience and skill. Every installation will be a bit different so it's hard to comment on how your install will go. It's mostly wireless so for existing construction the only wiring you need is to get power to the 12v transformer for the control unit. Once installed it worked great. I don't use Alexa or any of those systems so I cannot speak to that functionality. However the wireless transmitter, keypad and fobs all work perfectly. Not the best instructions.

Good things first:This system is very easy to configure, and the included instructions (despite being a little Chinglish) are comprehensible and easily followed.The magnetic lock seems solidly built and fairly strong. I didn't mount it and test the 400 pounds holding claim. Most of the lower end mag locks on inward-opening doors can be opened with a good swift kick, I suspect this one is no exception. It might be more viable on an outward-opening door, if there's no easy way for an attacker to get a solid grip to pull it.The two included handheld remote controls unlock the door instantly, and the included keypad works essentially as advertised. The RCs work up to at least 100 feet in a relatively open space, but being 2.4GHz they probably do not have good wall penetration.The keypad can be configured such that the door can be unlocked with a PIN and/or RFID card (yes, you can configure it to require both card and PIN for slightly improved security). There's also a doorbell button on the keypad that rings a chime on the controller, presumably so someone inside can screen and admit visitors.A push-button input is provided on the controller for an exit button (or whatever you want to use it for), it unlocks the door when pressed.Integration with the TUYA app works as advertised, but I probably wouldn't use that, since many of those cloud things are hard to trust.Keypad uses 4 AAA batteries (not included). The handheld remotes use 12V 23A batteries (included, and replaceable)Now the bad:This system is vulnerable to a variety of technical attacks, and one fairly critical non-technical one, which I'll address first.This is documented in the included instructions: if you remove the one screw securing the keypad to its base, remove the batteries, and press a little button inside there, you can reset the master passcode to its default value. You can then use the default code to change the door PIN, add RFID cards to the system, etc. This attack, if done by adding a card, would probably go unnoticed by the system owner until they needed to use the master code for something. This could have been done much better, e.g. by supplying a non-changeable unique override code that's included on a piece of paper with the system, and can be stored somewhere safe.The RFID component of the keypad authenticates tags based on UID only, so if an attacker has brief access to an authorized tag, the UID can be cloned to an emulator or "magic" tag, and then used to unlock the door (unless the system owner has required card+PIN). This could be somewhat mitigated by using additional data stored on the tag, possibly in encrypted blocks, for authentication. But that would make the setup a little more involved.The two handheld remotes, and the keypad, send their unlocking signal to the controller via 2.4GHz radio. This signal can be recorded and played back with a common SDR, thus enabling an attacker to camp across the street until an authorized user enters, capture the signal, and replay it later for access. Rolling codes would mitigate this.For the technically inclined, the radio IC used in the RCs and keypad is the Beken BK2461, a neat looking combination of an 8051 microcontroller with a clone of the nRF24L01 radio (the datasheet sections of the BK chip covering the radio appear to be heavily cribbed from the nRF datasheets, and the on-air signalling seems to be compatible). This might be of interest to anyone looking to modify or tinker with this system, or make a $3 handheld code cloner. At the very least I plan to order some BK2461 modules to play with.The included RFID tags (two cards and a small bag of keyfobs) are cloned MF Classic 1K, 13.56 MHz. As noted above, this system only uses the UID for authentication. It is capable of learning the UID of any relatively-compatible tag, if you want to use your own, such as a ring or implant.I might consider using this system for interior access control, in an environment where entry can be monitored independently and the point is to keep honest people honest. Not so much for keeping the criminal element out.I'd have given this 4 stars just on value for price despite the technical attacks, if it weren't possible to completely defeat the system from the outside by removing one screw and pushing a button. Given that, 3 is probably generous.

Cool product not sure about 400lbs but its an extremely strong magnet kinda suprising honestly. Can be set up to be used a bunch of different ways. Could be used in ton of different ways . Fairly easy to set up.

I use this as a backup system on a sliding barn door to my gun room. It was a little tricky installing it for that application, but that wasn't it's intended use. Recommended.

This thing has awful instructions I still cannot get the keypad to work. No videos or detailed instructions anywhere I have been trying to program it for 5hours now it’s ridiculous.
