A ten-gram collar tag with no SIM and no subscription, claiming a year of standby and real-time positioning.
What we take from it Thirty dollars for a ten-gram tag claiming 365 days of battery and "high-precision positioning". The battery figure is the one that settles it: nothing with a satellite receiver and a radio runs a year. No SIM is named, and no network is either.
A 10 gram (0.36 oz) collar tag, IP67, with no SIM and no subscription, claiming 365 days of standby. $29.99.
“Built with a high-capacity internal battery, it delivers an ultra-long standby time — tested to run continuously for up to 365 days.”
Ten grams of device, a year of running. A GPS receiver listening for satellites, plus a modem to send what it hears, cannot do that in ten grams — the Tractive Cat Mini on this shelf weighs 25 g (0.9 oz) and lasts five days; the Life360 weighs 29 g (1 oz) and lasts fourteen.
Whatever this is doing for a year, it is not holding a satellite fix and transmitting it.
The listing says “no SIM card or monthly subscription is required” and leaves it there. It does not say how a position reaches your phone — not Bluetooth, not Apple Find My, not Google Find Hub, not a mesh of its own.
Three other tags in this group at least name the network they depend on: MDTZULIK says Google Find Hub, Nilone and SxingUxing say Apple Find My. This one names nothing, which makes the architecture impossible to check and the coverage impossible to estimate.
“Simply scan the QR code in the manual to download the app.” No app name on the listing, for iOS or Android.
An app that is not named cannot be looked up, reviewed or checked for what it does with location data before the box is opened.
The one number here that is both published and useful. At 10 g (0.4 oz) this is the lightest device in the group — lighter than the 25 g (0.9 oz) Tractive cat tracker — which on a small cat is a real difference.
The network, the app name, the update interval, the Bluetooth range, and the water rating beyond IP67. The bullets are set in decorative Unicode characters rather than plain text, which is a formatting choice worth noticing on a page that gives so few figures.

The listing never says. It states there is no SIM and no subscription, which leaves Bluetooth through somebody else’s phone as the only remaining mechanism — but unlike MDTZULIK, which names Google Find Hub, or Nilone and SxingUxing, which name Apple Find My, this page names no network at all. Without that, neither coverage nor platform compatibility can be checked before buying.
A Bluetooth tag can. A GPS tracker cannot. The Tractive Cat Mini on this shelf lasts five days and the Life360 fourteen, both heavier than this and both charged by cable. A year of standby in ten grams means the device is asleep nearly all the time and listening rather than transmitting — which is what a tag does, not a tracker.
Not stated. The instruction is to "scan the QR code in the manual", so the app is only identified after the box is open. That makes it impossible to check in advance what the app requires, what it does with location history, or whether it is still maintained.
