To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The product is exactly as advertised. You get an RFID reader attached to a very simple locking mechanism. The locking mechanism is spring loaded and will forcibly eject the latch, which can either be useful or inconvenient depending on the application.
You can power the lock with either a (very short) USB cable or two AA batteries. The USB cable is standard USB 2.0 to a 2.5mm bipole, so you may need to hunt around if you're looking for a longer one.
Programming the lock is extremely easy, and you can program other 125khz RFID items like stickers. Perfect for if you want your unlocking item to be inconspicuous (i.e. not a fob or a card). You can pick up a pack of 10 stickers for $10 elsewhere on amazon, just search for 125khz rfid sticker. The lock comes with two cards and two fobs, but no stickers.
It is annoying that the program button is on the opposite side from the latching mechanism. That means that if you want to reprogram and you've lost your master card you'll need to drill a hole for the reset button or unmount the lock to get at the reset button. On the plus side, the device keeps RFID signatures even when the batteries are removed, although I have not yet tested to see how long it retains programming.
The mounting hardware is sparse, but functional. The hatch is stamped metal inside rigid plastic, so it won't stand up to any type of realistic forced entry. But that's to be expected. This isn't for high-security applications, it's for hidden applications or keeping honest people honest.
If you are looking to use this in a puzzle (e.g. escape room, puzzle box) then you'll probably want to open it up to disable the speaker so the solvers can't get extra information, and you'll probably want to buy a longer USB cord (or really hope the batteries don't fail).
There's not much more that one can expect from this item at this price point. If you're looking for an inexpensive way to hide a locking mechanism, then this will do the job.
Cons: 1) I could not buy more than one unit from the same seller. 2) the ears to hold screws to secure the lock to the wood are thin plastic...broke with a screwdriver 3) the 3m tape is handy, but it's very thin and light and didnt stick to my location (wood), so install was in need of a 3rd hand I didnt have.
Pros: 1) it programs, locks and unlocks like a charm... very handy and does what it says. Price was not terrible.
Overall... it is a working, hidden, keyless lock: what I needed. BUT the combination of pains such as cheap plastic where metal should be (a quick yank will literally break this thing), 3m tape that isnt guaranteed to do its job, And the fact that I have to buy from multiple sellers for each cabinet door really brings down the value. All in all I need this to keep the good guys out. Nor a high security lock and I dont intend to use it that way. That just meets the standard for me this go around.
I bought this to use as a hidden lock on a cabinet I was making. It would be mounted on a wall with no other access other than the panel door it would be holding closed. After reading the instructions I realized that "IF" the batteries should die while it was closed, there was no way what so ever to open the panel without tearing it off its hinges. It would stay locked. What a design flaw! After reading other reviews, (which I should have read before buying) it's my fault for buying this. The instructions say the lock is supposed to start beeping when the batteries are low notifying you to replace them but there's no way I would trust the batteries to last long enough for me to notice. I ran a test with this lock uninstalled with low batteries in it and it did alert me to that fact but it did not last the 50 opens it said it would prior to completely locking you out. Maybe ten times I opened and closed it before it locked up.
Otherwise the product is solid and works as described. I tested on the cabinet without actually installing it and it would release the lock through 3/4 inch of solid hardwood with the RFID card, but not the key fob. I would have really like to have included this in my project but instead went with some round neodymium magnets mounted into the base frame and cabinet door that hold it solidly closed.
Two deficiencies before I could even install it. The power to USB uses a headphone jack and they could have just hard wired the connection to the USB cable. If you fully insert the jack it did not get power. You have to pull it out slightly.
The wire to the box has a rubber cover that sides and exposes the wire. Not good.
I tested the device about 8 times and right after switching from USB power to battery.. it soon stopped working at all. It stopped locking and I could not get it to reset.
This thing works amazingly when you open the box and it is sitting on your counter, but the tolerances to mount it are just too tight. Using professional plastic shims that come in specific increments I shim the latch up 1mm and it's still too low, I shim it up 3mm and it's too high, I stack two 1mm shims to shim it 2mm and it's almost perfect but the latch won't swing in. I get the latch to catch and the door is either too loose (obvious movement when you touch it) or it's snug and the lock won't release. You finally get that all worked out and snap the door shut and because you used spring loaded hinges and the batteries come flying out the back of the unit and it is now locked with no batteries in it. I've spent two days trying to make this work.
I bought 8 of these to install in AirBNB for owner storage bins. After the initial challenge of installing the first one, I figured out a good system and the rest went in pretty easy. I did need to use some extra tape than what they provide, but also might have been due to the unfinished wood I was attaching to. Installed with standard #2 pine (1x10 boards cut into doors), the RFID card works - just barely through the wood. Its too much for the provided fobs though. I'm interested to see how they work in the longterm, i.e. 5 to 15 years as they were much more expensive that standard options. But with standard locks you see the lock and ruins the board and harder to put in. So - let see. Hope they continue to work well.
We got this as a trial wanting to lock an antique cabinet. Installation was a wee bit of a challenge, not because of the lock, but because of the cabinet. We did not want to change the appearance, or basic function of the cabinet. After a bit and a few choice words not fit for reviews, I had it installed. Man am I impressed!! Not expecting much at this price point, it is doing the job fantastically. The cabinet has not changed, but is locked and with a swipe of a card POP! it's opened! The only issue I have, and this was addressed in the documentation, is the cards work, but the fobs do not. This is very dense wood. So I will be ordering 2 or 3 additional access cards. Now I'm looking around the house to see where I can add more of these!!....Thank You!!
Update: When shopping on Amazon, we're often dealt with skepticism and legitimacy of various sellers, however, Alan from WOOCH will certainly leave you well taken care of. With my recent experience with Alan, he not only refunded my money despite my going over the allowed time for reimbursement but also insist I keep the item. I made no such request but accepted his offer. As stated in my previous review below, the item worked flawlessly but did not work with my dresser due to its design. I'm extremely satisfied with the customer service that Alan provided and will be a returning customer. Thank you, Alan
The RFID lock package came with a missing screw but everything else came undamaged. The installation was simple enough to install despite the lack of instructions provided. A paper manual with a list of items enclosed in the package along with a customer tip on installation and prior to installation are what is entailed on the one paper. I used the manual for reference but installation is all done with common sense. The end result, I was disappointed as it was not compatible with my drawer. The device worked as described as well as all the provided RFIDs but the design of the lock and placement made it impossible to install onto my furniture. Tip: if you have a stud planted in front of the dresser door from the inside of the structure then this lock may not work because it may cause the prong (the lock) to stick out, therefore, causing the drawer to not close all the way or lock properly. My dresser door could not sit close because of the wooden stud and the length of the prong. I'll be keeping the device to use with some other furniture since I've gone past the return/refund date. All in all, disappointed but hopeful.
