- Reviewed in the United States on July 25, 2023Style: 1 packVerified PurchaseUpdate 8/16: Unfortunately I’ve lowered review to 1 star. Super bummed to report that the tag is defective after only using it for about a month. It keeps going off on its own without me triggering it multiple times per day, so I took it off my confused dog. It also wasn’t working on apples “find my” app. Initially it was no problem, but when I sent it with my sister for the weekend who also has an iPhone, it didn’t update her location the entire time which was around 4 days. It showed her last known location as my house days earlier with no update, not cool.
After taking it off my dog I figured maybe I could use it for something else, so when I couldn’t find my phone I decided to try making it go off with this- no dice (and it ended up being less than 15 feet away, lame!). From the same location I used my Tile and my phone immediately went off for me to find it. For reference I’ve had my Tile and use it regularly for around 3 years now. I’ve only had to change the battery once. It’s on my keys and gets dropped and thrown around in bags a lot. This was on my 12 year old Pomeranian who spends most of her time napping inside and hasn’t gotten it wet or dirty for under a month and it doesn’t even work right? That’s ridiculous, seriously I don’t know if it’s a hardware issue or bad software, either way big time unimpressed would not purchase again or recommend.
Original review:
I got this for my senior dog to put on her collar. She rarely gets out, but it makes me feel better having this in addition to her microchip so I can check her location (she’s super friendly and sometimes my neighbors will take her for a short visit or a family member will take her on an errand and forget to tell me). It’s been on for close to a week now, and I really like that there’s a setting so she doesn’t accidentally hit it and set off my phone which is a nice feature.
I’ve been a Tile user for a couple years now which I also really like, but for this particular use I like that this one is smaller and quite a bit lighter by comparison. I will say it’s quite a bit quieter than my Tile, and only goes off for about 10 seconds (Tile goes off loudly and continuously until I deactivate it). I don’t think I would put this on my keys since sometimes they end up weird places like under a couch cushion or in another room and could be hard to hear, but other things I could see like maybe the remote. I am working on training my dog to come in for dinner when I set this off since she has a dog door to the yard, and it’s loud enough for her to hear well but not enough to scare her which is nice (and she startled pretty easily). I’m liking it enough I think I may get another for my sisters puppy as well since she gets out more often. I do wish it came with a key ring or something to attach it to anything with. A minor inconvenience, but still a bit annoying I had to go find something to attach it with. Overall liking it so far and may post an update later about how it holds up on my dogs collar
UPDATE: it’s been a couple weeks of trying to Pavlov my dogs with this thing. Every time I feed them dinner or a snack I play the little tune. Well last night i tried using it to call them in and it worked! I was so excited. I will say though the range isn’t that great- I had to walk over a bit closer to where they were in the yard and use it near a window, I’d say within 80 feet or so. But overall still really happy! Hopefully it keeps working, I’ll update again if anything changes
- Reviewed in the United States on November 24, 2024Style: 1 packVerified PurchaseI have used Tile trackers, but I wanted to try something that worked with the Apple "Find My" ecosystem, so I purchased two SmartTrackers. The "good" is that it was easy to set these up in the Eufy Security app and Apple's "Find My" app. But there are several negatives. First, the sound is not nearly as loud as the tile trackers, which is a consideration for those of us who have some hearing loss. Secondly, replacing the battery is much more difficult, requiring a small "sim tool" or pin to pry open the case. Lastly, it is more difficult to attach the tracker to my key ring because there is more material around the key ring hole. So one needs to pry the key ring open a greater distance. All in all, I prefer the Tile trackers.

5.0 out of 5 stars Nice Looking Quick Starter Personal Tracker
Style: 1 packVerified PurchaseIt's been just 24 hours I have started using this product. Quality and Finish of the product is good as well as it's very easy to use. It does integrate with Eufy app and Apple findMy App very easily within a minute. It's global tracking feature is no used yet however I am sure it will work fine given the fact that local tracking within the city is working fine. Only observation so far is that last location updates in apple findMy app are sometimes delayed over 30 mins. Also, since the product is new, it is not possible to assess the battery life for this tracker.

5.0 out of 5 stars another one that just works
Style: 4 packVerified PurchaseIm starting to get invested in the Anker family now. we have these trackers, a smart camera, scales, a recent Solix solar generator and the 5 port IQ USB hub from 2014 is still perfect. not a single item faulty yet.
the trackers have come in useful already. I bought these for mum. one on her car key, house key, handbag and one she keeps in her car glovebox. she's used them to locate all her keys and even her car on Gatwick airport car park as she forgot where she parked. she lost her phone and remembered the reverse find feature which plays a sound on the phone if pressing the button on the tracker. of course it was in her bag but she swears blind she "definitely checked the bag". oh how we laughed at her.
