Spend it wisely and never waste another's or your own.” ― Kyle Barger “Time flies fast, but it's good you are the pilot. Just control your time well away from hijackers. Save time profitably; Spend time productively!” ― Israelmore Ayivor, Daily Drive 365 Review: Works great worth the money plus batteries are included - Velcro is strong my receivers stay on. Wish the receivers were smaller but they stay on. I use them on firestick remotes works well to find them nice and loud family loved them use them all the time Review: Great Item - Took about 5-10 minutes to get all the batteries in them and test them all. 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! ## 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?
