Bottom line: looks like it will be useful, my daughter used hers and it did the job. We purchased this for us and gave a set to one of my daughters whose frequently misplacing keys. Until we set it up we were doing a key search almost every other day. Now, not so much; it’s like the keys know they’re tagged so they behave.

I’m guilty of losing my wallet all the time... In my defense, I usually lose it inside the house in a couch cushion or in some other place where I have to search forever to find it. With these neat little things, I can ping my wallet with my phone and it’s loud enough where I can here it even if it’s across the house! It’s nice knowing that if I misplace my wallet, I’ll know where I last had it and that I can find it with these things! I haven’t had them long enough to know the battery life, but the battery’s are replaceable so I’m not too worried about it!

This thing is awesome... helps my mom a lot. She misplaces everything from her keys, phone to her pocketbook, you name it. We use it everyday finding her things with the tag tracker on it and it worked.

I seriously wish I got these a long time ago because I probably wouldn’t have lost my nowhere to find keys!!

I love that the batteries are replaceable. I bought these so my wife would stop losing her wallet and keys. Installation was quick and simple, now she can’t even walk away from them without getting an alarm! Thank you!

This product is good, with some drawbacks. The device itself is working very well as expected, with fair battery life.

I LOVE THIS. Easy set up, easier to use. I can find my phone even when it is on silent, which is usually is. That is genius!

The tracker works with the iTag one program. Requires fresh batteries. When the keychain loses contact with the base, it gives out a loud alarm on the phone. There is an option on the phone to turn on the keychain detection signal. Then the keychain will signal with the frequency of your approach. There is the possibility of detecting the keychain on the map.

Turns out if you give this to your wife and you need to find her, this work. Though I didn't buy them for that purpose. It just happened that I misplaced my wife in a department store and she had her keys in her pocket. So, rather than call her, I just activated the app and located her that way.

I love this Anti-Lost Tracker. This is the second time I am purchasing it. I love that it allows to replace batteries. It allows you to quickly find your keys, whether if they are misplaced at home in another room or left in your car

Fast delivery. Packed well. It works only via Bluetooth. It connects easily and simply, as described in the instructions, you need a new battery (it was mention in the description that it's not included). The program isearching, downloaded from Google Play and it found device right away. The tracker triggers the removal of about 15-20 meters from the phone, alarm is quite loud and the phone emits the sound of the alarm. With the program iTag one it works to search for items. Generally, I am very much pleased, thanks to the seller.

Delivered super fast. Bought one for my cat and one for the keys.

They do work. And I love that you can find and ring your phone (if it’s nearby like in the house, purse, car).

I bought same trackers earlier. I used it to keep track of my keys AND my cell phone (which I can ring from my keys). So I ordered 4 more packs this time. We hid one in our vehicle in case it's ever stolen, one in our travel trailer for the same reason, and attached another to our dog's collar just in case. I gave one to my son for his keys, and used one for my second set of keys.

I downloaded the app, I activated two of the smart trackers and they are working just fine with my phone. I use an Android device phone and it's nothing fancy. Once I set up my work keys, I tested it out at work beautifully. Then I set up my car keys, followed all the steps and that worked well too. I'm thinking to order couple of more to give away as a Christmas present. I think all the receiver needs to do is download the app, create an account, and then they can just use those smart trackers the same way I'm using mine.

I lose everything - keys, handbag, wallet... so i can not imagine my life without Anti-Loss Tracker now...nice to see that you can change out the battery. I am a total fan of smart tracker now.

It matches the description, the sound it emits is annoying) but meets its function.

Eight days ago, I could not find my car key, so a friend came over, searched my car and found it where I would never have looked. It turned out that getting out of my car, my car cord caught on the door, the ring stretched and the key ended up in the passenger seat. I decided it was time to put something on my keys so that when this might happen again, I can find the key. I got a four pack, and have one in my wallet bag, one on my car key ring, one on my house key ring, and one in my laptop carrying case.

I probably use them about 20 or so times a day and have probably started to depend on them a little too much😬

Works well. The battery lasts for a long too.

It works well. I attached it to my cat because I moved to a new area, if he wanders too far off my phone will ring when the tracker disconnects. When it disconnects, the tracker itself makes this obnoxious beeping sound, so if my cat is lost and in someone’s yard someone is bound to hear it. My cat is used to wearing the collar with a little bell, so he did not really mind having the tracker on his collar. I realized that I feel much easier about letting my cat out now, it used to be always at the back of my mind - what if he gets lost... Thanks to the smart tracker, it's not a problem anymore!

Easy to use. Got on time. Very affordable, works great on my pet. Will buy again to utilize on Keychain and kids backpack.

I purchased one of these with hopes of attaching it to my dog, so if he wanders off, I could find him easily. It works in combination with a smartphone app (I used version 2.3.9 on iPhone IOS 8.4.1), which does most of the work. I can see this being useful for locating your car in a large parking lot. After configuring and connecting the app/device, you would click once to mark the location of your car. Then, when you want to find your car, open the app and locate the setting on a map. Voice memo works, but I can't find a practical application for this, except for a voice reminder (which could be done without the device).

Bought these for my mom, she's constantly losing her keys and phone, so this was an awesome gadget for her! Wish they made a smaller version to attach to her glasses, so she wouldn't always be losing those too!!

Very happy with this purchase!! The device connects to your phone and does some awesome things like if I loose my phone I can press the button and it will ring!! Also I can attach it to things I dont want to loose and I can ring them from my phone so I dont loose them. And most importantly if you forget something and you go out of range it will buzz! Great product for great price
