Every one of them work perfectly. You do need 2 AAA batteries. The Alarm doesn't hurt your ears but its loud. They are bigger than I expected, about the size of key FOB for the car. I used the supplied Velcro for sticking to things, had to unstick one to move it and it still grabbed very well. They fit nicely on a key ring. Range seems good, worked fine from my living room, down a hallway into the bedroom with the door closed. For people that say cheaply made, I disagree, for the price it's a great deal. Would you rather it was metal? Will pay for itself the first time I misplace one of 6 items and I hear it Beep. Or if the power goes out I can find my Black flashlight in the dark. I didn't get anything for this review, just tickled with my purchase. UPDATE after 6 weeks. I never lose my keys but it happened. Searched the house and basement with this in hand, no beep. Remembered going out to shed yesterday. I walked out there and stepped right over them in the grass. Pushed the button and there they were. Don't know if I would have found them without this before I mowed the grass. I am so thankful I purchased this item. It is worth it's weight in Gold! Only buy this item if you hate pain and pressure!

This will help immensely you just go over to the wall where you’ve attached this to the wall where it won’t walk away and then push the button and then you can find whatever it is you’re looking for I have it on my purse my keys, my phone my earbuds,,my husband has it on his extra set of keys, yes yes I’m a little rough. I did have to tape the bottom cause I seem to hit it against something and battery falls out. The others hadn’t, but that one has of course the one picture of course anyway, it works well worth the money. ## Features - Portable Design with Thinnest Receiver: our 6 0.24-inch thick SIMJAR receivers can be attached to TV remote controllers, luggages, mobile phones, glasses boxes, wallets, pet collars and more - Advanced Fabric Transmitter & Built-in Flashlight: Are you tired of cheap plastic material?
