Let me start by saying this tracker has serious potential. The LED light and loud sound features genuinely saved me when my golden retriever bolted after a squirrel at dusk. The waterproof claim holds up too - we've been through rainstorms and muddy puddles without issues.

The app's health monitoring is surprisingly detailed. I can track my dog's daily steps (yes, dogs have step goals now!) and even calorie burn. Seeing his activity spike after dog park visits never gets old. The safety zone alerts work flawlessly - it pinged me when my escape-artist pup dug under the fence last Tuesday.

BUT...the connectivity is maddeningly inconsistent. Like another reviewer, I experienced the mysterious 10pm shutdowns that terrified my dog. The instructions might as well be hieroglyphics - figuring out how to remove the magnetic cover took 20 minutes of frustrated prying.

The real dealbreaker? Spotty signal in rural areas. During our camping trip, the tracker showed my dog wandering in China while he was literally sleeping at my feet. Urban users seem to have better luck based on reviews.

Battery life is a bright spot - lasts nearly a week between charges with moderate use. The adjustable collar fits my 70lb dog comfortably, though smaller dogs might find it bulky.

Final verdict? If you live near cell towers and have patience for tech quirks, this could work. But for rural pet parents or those needing reliability, keep shopping.
