Key Finder Pair, Indisputably The Loudest with Long Life Replaceable Battery

I love this device, but now I like it even more1.You see, I lost my keys the other day, just days before a trip to my home in Mexico. If I couldn’t have found them, I’d have had to cancel my trip. So, I got out the Key FInder device and pressed its button twice. It went off, but I didn’t get a response to it. So, I hit it again, it made an unexpected sound and died! further double presses of its button produced nothing!I was pretty freaked out, as I had no idea what I could now do to find them. The lady, who sits my house, and I searched for 2 hours, and nothing! So, I gave up and went to Amazon to see if there was a warranty o the Key Finder. I not only learned that there was a warranty, but I also managed to find a phone number for the makers of it, as well as doing a web search and finding their web site.So, I tried to call them, but only reached voice mail. I left a message there, and I also sent one through the message portal I found there. Not 15 minutes later, I got a call from a guy who, I suspect, is the designer of the device & the founder of the company. He explained to me that these devices work by actually ‘listening’ for the tones that one hears when the button on one is double clicked. The other one hears that tone, and responds with the same tone, so it can be located. He also pointed out a page at his web site, where one can click on a link, and whatever device you’ve accessed that web page with, if the device has the ability to produce audio, will generate the necessary tones, so the Key Finder will hear it and respond!So, I got out my smart phone and went to his web site. When I clicked on the link, my phone emitted the needed tones. So, I began to search for the keys with it. But, I still got no response in the house, upstairs. So, I went down to the garage and tried it. I also got no response. But, then I remembered something the maker thad told me, about how he sometimes loses things , and his wife always asks him if he’s looked in the refrigerator! I remembered that I’d been showing my house sitter where she could find food, and that I’d opened the big chest freezer in the garage. So, I walked over to it, and as soon as I lifted the lid a crack, I could hear the thing going off! My keys were hiding under a bunch of Salmon fillets!So, not only is this a great device, but it has some of the best, most caring support, that I’ve ever encounter! They're sending me a replacement for my failed unit under their warranty. Plus, now that I know about the ability to use my Smart phone to locate one of them, I can use the 2nd one for a 2nd set of keys! No longer do I need to keep it in a drawer, where I can always find it! I’ve recorded that tone onto my Smart phone, so now I don’t even need to load the web site to use it!There is one caution I would give you - routinely change the battery in the units, and do it annually. They won’t be fully used up yet, but other devices that are less critical can then use them until they’re expired, so they don’t go to waste. You surely don’t want them to expire in the units, only to discover that, when you’re trying to find you lost keys! If the unit on the keychain has depleted its battery, you will not be able to locate them! In spite of that - HIGHLY RECOMMENDED!

I have had the KeyRinger brand for years, and I love mine! Yes, NICE and loud, adjustable, and things are findable many feet away, though many of the walls of my home or business (sometimes I have to walk around a little...) For the past several years it has been the XL model. A few years ago I took the time and patience to learn how to assign a number to each and "set" them: then I have an entry in my phone contacts where all the labels are listed, and the URL for the website for calling them. My car keys are #1, office keys are #2, purse is #3, and so on. I pair my insulated stainless steel tumblers for coffee and for ice water with Gearproz HydroNet carriers and keep track of those too. The customer service is great for Keyringer--someone even answers the phone or responds to email and coaches you through. I had to have a warranty replacement once...but wow, a TWO year warranty for an electronic gadget is generous. I have some working well that I have had for years (yes, keep those batteries up--but even they last quite long in the newer KeyRingers...typically a year or more).One of my KeyRingers wore out after probably four or five years of use--understandable--I cheerfully went online and ordered some more to support this business and as one of the best bargains of my life.

Sorry my inner Gen-X is showing. But honestly that is sort of the same premise of this gadget. A double-click on one finder plays a magic tune, and the other finder responds (just like Green Ranger summoning his Dragonzord with the Power Rangers flute). I guess its sort of related to the old Clapper (again, Gen-X) where you clap your hands to produce a sound and a light goes on - same vibe.Personally I refuse to use Bluetooth finders, because I've had my phone battery die in mere hours with Bluetooth perpetually on. And the RF finders I believe have lower effective range, although you can make the argument that since this is sound-based, in a noisy outdoor environment, or city street, it may not be able to "hear" the tune.But I love this. I made a shortcut on my cell phone for the KeyRinger webpage that has the "Call All KeyRingers" button so even if I lost both items with finders - I could just play the magic tune and they both start responding, and it really works!The sound does get increasingly loud. Yes I guess it could hurt your hearing if not turned off. It scares me a little bit that to deactivate the sound you have to successfully locate the loud one and press it. Imagine if it falls behind a fence or behind a heavy stove and you can't easily get to it. Then you're stuck with it ringing for 15 seconds. But if the point is to hear a loud sound to find an item, clearly this is mission accomplished.I really like this gadget, its a refreshing change from the Bluetooth, RF, and GPS SIM card type finders and trackers that is a welcome one. Its unique and straightforward technology that really works well provided your home or environment is quiet enough for the audible activation to work. I would probably want one even if I didn't need to find things (though I'm forgetful and do) just on the scientific premise alone - its just that cool.
