Maybe with line-of-sight that range is realistic, but in even a moderately wooded or brushy environment the range is more on the order of 30 feet. On the plus side, at least this is not dependent on cellular service, nor does it require the use of a cell phone to work. (I really hate stuff like that.) Instructions could be better. Not everyone encounters this type of battery often and the question arises "Which side goes in and which out?" I guessed "side with the letters on it out" and that worked. The little rings that connect the beepers to whatever are fine for something like keys, but if you're going to put it on a dog collar you might want something a little more substantial, like maybe a tiny chain linking link (good luck finding one small enough) or stainless rebar tie-wire, depending on circumstances. I got these because my dog has pulled off her expensive Blazin' collars several times while engaging in her favorite sport of rolling around tall grass and worming around in bushes. When it happens again, I hope this will help me recover the collar. I don't yet know what happens when it gets wet. If it fails real soon, I'll come back and downgrade the stars. If it lasts really well or stands up to severe conditions, I'll come back and up it to 5. Time will tell. Meanwhile, I'll look for one with more range. ## Frequently Bought Together - Key Finder with Up to 131ft Working Range in Open Space, Simjar Wireless Remote Control RF Key Finder Locator for Keys Wallet Phone Glasses Luggage Pet Tracker - 4Pack Case for Roku Remote, Cover for Hisense/TCL Roku TV Steaming Stick/Express Universal Replacement Controller Silicone Sleeve Skin Glow in The Dark Green Sky Purple Red - Reyke Key Finder, 80dB+ RF Item Locator Tags with 131ft.
