GirafusPro-Track-tor - Ultra-Lightweight Cat Finder (ONLY 0.28oz) - No Monthly Fees - 1600ft Range RF Tracker - Works Where GPS Fails - Find Hidden Cats Anywhere

We have an indoor cat that likes to sneak out and run. This location device has proved itself on more than one occasion. We still have our beloved cat because of this device. It's a bit fiddly and requires some maintenance but when you are searching for your pet you will realize how much its worth it...Tips:1) The rechargeable batteries are a pain and need to be recharged, changed, and watched frequently. Instead, try CR2032 Battery Lithium Coin Battery. CR Lithium 3V Cell. They are single-use but are cheap and last as much as 6 weeks. By a pack and add a reminder to your schedule to change them out.2) Change out the receiver's (base device) batteries at least every 6 months (2 Tripple A) whether you think needed or not.3) Test the tracker on your pet's collar when you brush/ pet simply by pressing the little button on the back edge of the tracker tag. Look for the red light on the tracker tag. No red light, change out the batteries...4) Read the instructions carefully. It's worth it.5) If the casing on the tracker tag does not screw down perfectly (or if your pet likes to bite at the tag now and then) reinforce it with a square of duct tape being careful not to cover the red light or the button in the back edge. This will hold it together better and help keep your pet's teeth from penetrating.6) When trying to locate your pet as per the instruction note you can briefly press the appropriate tracker button on the receiver and in a second or two the tag on your pet will make a brief high-pitched beep for you to listen for. This will help when you are getting close to the pet but are not exactly sure where they are.This is all a hassle yes but again, so worth it when the day comes you need it... Be disciplined about it and keep up with it, just do it...

Short version: tracker was lost on first use.Details that may help you have a better experience:To be fair, this is the only tracker I've ever used, so my expectations may have been different if I tried some inferior ones first. I spent days pouring over reviews and technical specifications before choosing this tracker. I knew I didn't want Bluetooth (range not good enough), and I didn't want a monthly self-renewing subscription. I also didn't want a battery that expired in less than a day (many GPS trackers) and then needed to be recharged. I eventually concluded this one was the best option, and maybe it is, but it didn't turn out to be the right fit for me.The instructions were in the box - you needed to read one to set up and another to learn how to track. I found the instructions to be good and easy to follow, but if you become confused, I believe there was also a video online you could view. Everything was packed very well, and everything other than a collar or harness,and a wall charger for the USB is included. They even included a tiny screwdriver and extra screws.I charged the tracker tag batteries, then put one in one of the tracker tags. Here's where I encountered my first issue. 1) It was almost impossible to get one of the batteries out of the charger - I'm afraid the efforts required to remove it would cause the charger parts to have a very short life.2) Getting the tracker tag and, (even worse) the handheld receiver apart to add or remove batteries is very, very difficult. It's only a light plastic and would be easy to break. I had to use a very thin prying tool.Once I put it in and followed the instructions for initial pairing / set up (quick and easy), I put the tag in the included molded silicone tag holder and attached that to the collar. After the cat had been gone most of the day, but while it was still daylight, I turned the tracker receiver back on and tried to find the cat / tracker tag following the directions for turning this way and that to get the best signal.I went to where it led me, but once I was (supposedly) close, it couldn't seem to give any further input. I then used the chirping feature, making the tag chirp, but it was still impossible to find the location of the high-pitched chirp. To be fair, the lack of tracking ability once close was indicated somewhat in some of the reviews I read, but they apparently didn't have the problem I had where the tracker could never be recovered/found. If, once within ten feet of it, your cat or dog will always come to you when called, or if the cat or tracker is in a very open clear area, you will probably be able to find it from there. Unfortunately, the area it led me to was a cluttered shed, and the tracker could never be found. When I next saw the collar, the silicone case was still in the collar with no tracker in it.So 3) the silicone case is NOT going to hold the tracker in, and if you rely on it to do so the tracker WILL be lost. You may wish to do as a previous person indicated and wrap the thing in tape, but that's going to get old fast when you keep having to take it apart to recharge the batteries.4) I originally felt that if the tracker did get separated from the animal, the ability to track, the brightly-colored collar I used, and the chirping feature would result in its retrieval as long as the batteries had a charge. This turned out not to be the case.
