Key Finder Upgrade by Calerix, Anti-Lost Tool for Wallet, Purse, Cell Phone Locator, Car Key, Pram & Pets Tracker, Bluetooth Key Finder with Alarm, GPS Tracking System Wireless Key Finder (Green)

I have this on my bigger dog and it doesn't take up much space on her collar. We've had issues with her getting out and now when she roams the neighborhood, we know exactly where she's at. We no longer use it on her as we have a new fence but I have this to help keep track of my kid while in high school. I placed this on his house keys and now know when he's at school and when he's at home. What's nice is it gives you real time location tracking. No delays at all. In the app, you can zoom in and I can clearly see what streets he's on and watch him move.

Easy to use and works well. It's small, and inconspicuous, so it doesn't bulk up your key ring, or become the main focus. It's come in handy already when I misplaced my phone..the beep isn't deafening, but it's loud enough to get the job done. I had gotten one of these for my daughter for a gift, but then decided my having one as well, might be a good idea. I'm notorious for setting my purse on the floor under a table when we go out somewhere, and then walking off and leaving it. I'm hoping this will help to avoid that.

Unlike others, I don't lose keys, I forget my phone a lot when I leave the office. I want the anti-lost feature that will alert me when my phone is not with my keys. This is the 3rd one I tried, so far the best one. The bluetooth stay connected and will re-connect on its own without having to do it manually. But there is one thing I don't like. In order for the key finder to alert me that my phone is not with me, I need to wake up and log in my phone before I take my key finder away. It's kind of defeat the purpose. If I remember to wake up the phone, I wouldn't forget to bring it with me. But luckily as long as I do it within a couple of hours before I leave, it works fine. So serve the purpose with a little inconvenience, overall it's a good product!

This product has already helped my wife to not lose our second key to our new vehicle. the sound it makes will enable her to find her keys if she leaves them sitting somewhere. well worth the small cost to not have to pay the large cost to make another key

It works as advertised. It uses Bluetooth technology so range is limited, but for people who loose things easily in the home, this product would be quite useful. Set up instructions seemed easy but it left out a step in the software set up. I had trouble with this, but after viewing a couple of how to videos on the UTube, I learned how to set it up. I don't know about battery life, accuracy, because I haven't had this product long enough to tell.

I really like this item. It comes in very, very, very handy. I recently lost my key FOB to my jeep. Thankfully, I had just attached this to them, and found them in my other coat. So, it paid for itself right there. This will go quite a long ways away. It will make it through a wall (or floor) and all the way across the room. The battery is even included. So, that was really nice. You have everything you'll need to set it up. It also comes with precise and clear directions with pictures. It's small enough and sturdy enough to withstand enough rattling around in my pockets at work. It's built good and at a great price, I don't think you can go wrong with this! It made a great early christmas gift!

Pros: I've already used to find phone and keys half a dozen times since receiving. Hallelujah!! Small, lightweight, effective. Delighted. Cons: One month later, the battery is dead. I ran across another product for 1/4th the price with THREE trackers in the box. Summary: So, love the tracker concept. Like that I can put this one on a key ring, and that it has a replaceable battery. I didn't love having it die in less than a month, or learning that the price seems so high. So, a three star.

My husband has started playing with this. He keeps saying, "That's really neat." The app was easy to download and get working. The GPS identified that it was located in our house, but my husband says he wishes it were more sensitive. It seems to work pretty well so far, except the bluetooth had a hard time re-syncing. That could have been my husband's phone, though.
