This is a very mediocre product. Little kid walkie-talkies work better.

I followed all directions to start the search and started in the back yard. It would tell me to go a particular direction and the green light would be on and it would beep super fast as if the cat was right in front of me, but she wasn't. Then I would turn around and it would tell me to go in the opposite direction, and the same thing happened, but she wasn't there either. This had me going in circles outside.

I knew my cat was in the closet in the house, so I thought it just couldn't tell she was inside. So I went inside to see if it would lead me to her. It worked better in the house, but again kept telling me to go in opposite directions and would beep like she was there with the green light, but she wasn't even in that room or that side of the house.

I went into my room where I knew she was in the closet and I held the button down and her tag beeped. So the direction part doesn't work at all, but the tag will beep when you are supper close to it (i.e. in the same room). Its basically like calling your cell phone when you can't find it. I can't believe I wasted $90. I feel like an idiot thinking any of these products work.

Works great. Original batteries died instantly once I communicated with seller they let me know that that it needed the rechargeable 3.7 volt batteries which they provided and it had not originally come with the item. With the batteries they provided the tracker works great. I've had to use it twice to find the kitty that was hiding in plain sight and once to find the collar that the kitty lost. I highly recommend this tracker. Great customer service as well.

I lost the handset for my Loc8tor Pet, and it was no longer available to purchase, so I bought this. It works at a far greater range than the other product, which is the best thing about it. If there's no substantial obstacle, it beeps when my cat is some 1/4 + mile away in the forest. It's harder to pinpoint direction, though, and can be as much as 20 degrees off either way, which is substantial, but with practice you can learn to narrow it down a bit. The handset is bulkier, and seems to be made of cheaper materials, but the thin, sleek design, black color, and small size of the Loc8tor Pet handset probably contributed to its loss, so the bulkiness and light colors can be an advantage in a way. The 2-piece tag, which slides apart for battery insertion often slides apart a fraction without my help, possibly knocked apart when the cat scratches himself. When this happens, it renders the whole setup useless. It's better than nothing, works most of the time, and is a lot smaller & cheaper than any GPS system I've seen.

I was excited to find a product small enough to use on a cat collar with a range that's actually useful. This product works very well if you have a little patience. It takes practice to sync the tags with the base unit. Watch the online video a few times. They are a little finicky, so if you expect them to be perfect you will be disappointed. Sometimes the tags will randomly reset (possibly from cat activity) and you have to sync them again. I bought four tags because my two cats lose their collars sometimes, and this proved very useful because I can just swap in a working tag without having to sync all four again.

In our typical neighborhood with houses, trees, etc. and considerable variation in terrain, I can pick up a signal at least 200 yards in any direction; this is the farthest I've had to look so far. On level ground with fewer obstructions it may well reach the advertised range. It helps to block the base unit with your body when you try to establish direction. It takes a minute to acquire the signal for each tag, but I've found that it does this even if you don't "calibrate" the base unit.

My cats (12 and 17 pounds) don't even seem to notice them. It's worth every penny for peace of mind.

I really like this unit. My cat doesn't escape much so that battery has easily lasted over 2 months. The unit is small and the small silicone unit cover is great. Finding my cat with this unit isn't the easiest (especially in my apt when he is hiding) but I get such a piece of mind knowing that this thing is really reliable at getting me close to him. My giving it three stars is because the tracking chip is made very cheaply. Before you do anything, keep in mind that to open the unit, it has a very delicate slide mechanism so be patient.
