I'm using this as a lock for my front door. Instead of buying a kit, I bought individual pieces because the kit didn't have what I needed, like the Z bracket and a fingerprint reader, but did have stuff I didn't need like cheap power adapters and wireless entry.

I managed to get a perfect alignment of the armature plate mounted to the Z-bracket and this magnet mounted to the trim above my door. I first removed the trim, added extra wood behind the trim, and used many long nails to secure the trim so it wouldn't come off if somebody tried to force their way in. The magnet goes on the trim above the door, and the Z-Bracket goes on the door, but needs to be mounted level with the trim, so I added another piece of wood to my door as well to bring the mounting position of the Z-bracket level with the magnet. By getting it all aligned properly, there's no way anyone would force their way in without breaking the door. This magnet holds the armature in place with far more force than my door could handle.

The only reason I'm docking it a star is that I had to drill a hole in the magnet casing to allow the wires to come through the trim into the magnet without exposing the wires. The provided hole is for mounting the magnet under the door trim instead of on it. That only works if the door opens outwards from the side the magnet is on. My front door is like every house door I've ever seen, and opens inwards, and of course the magnet needs to be on the inside. They could have easily provided another hole for mounting to doors that open inwards without exposing wires to tampering.

I purchase this lock as a secure lock for a hidden door walk in closet where i choose to hide my valuables. I chose magnetic lock for the low profile look (no obvious sign to see like a knob or keyhole the will defeat the purpose of being a "hidden door"), Locking power, and no moving parts so its quiet and no parts to lubricate or break down. My setup is quite simple the lock, an old a/c adapter from my sirus radio, and a Christmas light remote to turn it on or off. I also plan on plugging the a/c adapter to my old UPS so that the lock would remain secure for at least 3 hours in a power failure. Now for my Pros and Cons

Pros:
Relative easy to install. All you need is a good drill and you can get this up in no time
Holding Power. My door would give way first before I could separate the plates, it really is held in there.
Quiet Operation. You can engage and disengage the lock without anybody noticing you did.

Cons:
I did say relatively easy to install but you still need basic skills as installing this you do need basic electrical and wood working skills.
You need to properly align the base plate with the magnet for it to hold tight, any misalignment of the plates will result in less than satisfactory result.
The unit would run warm (which is actually good in cold weather to prevent lock from freezing up) and would consume around 5W of electricity to operate

All in all a great buy for me and if in your application you think this kind of lock is best for you its money well spent.

We bought this after having lots of problems with an electric strike and it does the job just fine. We'd recommend using a power supply with battery backup in case of power outages, and we used a PIR motion sensor as our request-to-exit (REX) input device.

Strong lock. Have to also order Z-bracket for correct wt limit for interior swing doors. The electric connection screws are a little fragile as RN most all these type products. You want to tighten your connections to keep the wiring from loosening up & coming out without stripping your wires. You will want longer screws/bolts for better hold for break-in concerns. 3 inch bolts are recommended on security bolts( your door is most likely not that thick, but measure it & take install bolts to hardware place (Revel ACE is always helpful with this) for longer screws & bolts. Works great so far on initial testing for access control system for my church. Will repost after install as update.

I am buying this electromagnet with a different use in mind, so my review is for that application. The reason I am buying it is because I will be using it for experiments involving magnetic fields including this product and magnetically active fluids.

This electromagnet and its steel plate are very heavy and well constructed, I can report that the magnet itself will exert a lot of force on the plate once it has been connected to a DC source. The force is enough that if placed correctly on a door would make it extremely hard for somebody to open, which is intended purpose of this electromagnet. However, it has to be used with the right kind of system which is not included here, but might be suggested in the products that go with it.

Very pleased with this magnet. No problems installing it.

I especially like the wire blocks. Some magnets have pre-attached wires that aren't long enough anyhow.

I used the SECO-LARM E-941S-1K2/HQ Armature Plate Holder. Wow, did that make my job easier.
