It helped me when me or my son loose our keys just a mash of the button we found it

This device is pure TRASH! There's literally nothing I like about it, because it doesn't work. The app doesn't function correctly and is littered with broken English and misspellings. I finally lost my keys and depended on this device to find them...IT DIDN'T! Bluetooth wouldn't even connect, and the app constantly froze. This is worthless and a waste of money. I'm pretty sure I threw away the packaging, so I probably won't be able to return it.

Simply stated... it doesn't work. Though instructions poorly written, I managed to get the app and key finder connected via Bluetooth. I also managed to intentionally trigger the alarm in order to find the fob/keys. HOWEVER, the fob would also beep on its own... without being intentionally triggered. The fob was continuously re-syncing with Bluetooth and while this occurs, it beeps... and beeps... and beeps. Turning off the app only makes the fob beep more. Only way to stop the beeping was to turn off the actual fob, but what is the value in that if the device is off and my keys are lost?! It is definitely being returned.

Would not let me set it up in the app. Battery was completly dead. Tried to replace the battery with a new 3 volt and the battery is a different size and wouldn't fit.

I bought because of the good reviews but they were all fake and part of a paid promotion. Terrible company!

PIECE OF CRAP. DOESNT WORK. DONT WASTE YOUR MONEY

the item came not working and unsupported on the app

If I could give this junk piece of plastic nevative stars I would give it about -5 stars. From the second you download the app, nothing works. First off, The instructions in the box dont go with the app. Its missing a whole menu item. That menu item just happens to be the one you set it up with. The app is 20% done so where there actually are icons to push to open, you do it but they are completly empty. Nothing is there. Nada. Zilch. There werent any reviews on here yet to warn me and I wish I would have been able to look at the reviews of the app before buying, but you dont know what app it is until you open it. The app is called the “Monster Key Finder by Lenze Technology”. Read the reviews before purchasing. The only thing this thing does is beep. Not at 75 ft away, but 40 feet sometimes, 30 sometimes or if its really in a bad mood, youll get your phone 10 feet away and it just beeps and beeps. I can only imagine what it would do if you used it to track your luggage or backpack. The TSA agent would tear your bag open just to shut it up and you'll be put on the no-fly list. Needless to say, I am returning it first thing tomorrow and warning you to STAY AWAY!!!! Or at least dont say you werent warned if you do get it and then have the same experience I did. Because you will. I promise.

DO NOT BUY!!! The first review on here is exactly correct. I downloaded the app and it doesnt even have the button you set it up with! According to the first review i guess the app is still being developed? Why would you sell it then? Lame
