Range in cluttered area is not great & iInstructions could be better, but works well otherwise.
Note the "in open area" qualifier to the range claim. 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.

WOW. BUY IT
Honestly, this is one of the best purchases I have ever made. I was so fed up with facing all of the anxiety and endless searching that comes with lost keys. I lost mine several times each month, making me late to work as well as getting my kids to school. This was such an easy setup. You simply attach the alarm to your keys and keep the remote somewhere you know you will remember, works like a charm every time. The distance is pretty far, too. I have used this alarm while in my kitchen; locating my keys in my car, outside..you do have to make sure the background noise is dim but the alarm is decently loud. SO WORTH IT.

Good
I was a bit disappointed at first with this product because it arrived and didn’t work. No matter how many different pairs of new batteries I put in there, I just couldn’t get it to work which was extremely disappointing. However, when I started my return process it gave me the option to just get sent a new one instead of just opting for a refund on my purchase and I’m glad I did. Not only did the new one work, but it arrived really fast and it is most definitely useful.

Bulky.
Very bulky. Wish they were a bit smaller. They don’t fit on Amazon fire or Apple TV remotes. You can only hang them if you have a remote cover. Can’t change the tone type or volume. But they do work.

Locator tags passively drain the battery and die.
Product is decent at first. Tags are reasonably small and easy to attach to things. Remote is nicely sized and has decent range and even includes a little cradle to set it on a shelf. Tags beep pretty loud when activated and it works even when they're buried inside of a couch. That said, there is a massive design flaw pretty much ruins this entire product. The tags that you attach to things seem to have a passive battery drain at all times so all of my tags were dead within a couple months meaning they were useless when I actually needed them. Sure, you could constantly replace batteries but that kind of gets expensive after a while especially because the tags all use those cell batteries that cost two or three bucks a piece. So now I have four useless tags and a remote and my choices either replace the whole thing with something better or spend 10 bucks replacing all the batteries which I will have to do multiple times a year.

This product has made an amazing difference in helping both myself and my partner keep track of our house fob and keys. Previously, we often struggled to locate them before leaving the house, but now there is no more worry about it. I also appreciate the smaller design and the use of colour-coordinated attachments. The is simple to assemble and operate—if I can use it, anyone can! Our everyday routine has improved significantly thanks to this product. Its reliability and user-friendly features have truly made our lives easier. No more yelling "where are the keys". It's a much calmer household now and now if we forget we just use this. It's perfect! You can also use this product with your remotes for the TV as well as other things but we just haven't tried anything else yet. The only drawback is be careful when using if you have a dog or animal, the sound to find your items is loud which is a great thing but just teach your dog or pets that it's coming - lol.
