An Apple Find My collar tag with a speaker that can be sounded from the phone, IP68, and a claimed twelve months of standby.
What we take from it The third brand on this page to sell the same OEM tag: Nilone calls it F 18B, SxingUxing calls it F18B, this one is the F18A. What it adds over the two already published is a speaker you can trigger from the phone, which is the feature that actually finds a tag indoors. What it shares with them is the contradiction: it pairs over Bluetooth and then promises global real-time positioning.
A Bluetooth collar tag that reports through Apple Find My, with no app and no monthly fee, IP68, a claimed twelve months of standby, and a built-in speaker. Supplied with a keychain case and a collar case, and an 18–30 cm (7.1 to 11.8 in) adjustable strap. $22.99.
iOS only. “Fully compatible with iOS/iPadOS 15.4+.”
Manufacturer reference F18A. The Nilone tag published on this page carries “F 18B” and the SxingUxing “F18B” — one OEM, three brands, three prices. That is ordinary in this niche, and it is the reason to compare the listings rather than the names.
What separates this one is in the third bullet.
“Activate the built-in speaker through the app to trigger a loud beeping alarm. Simply follow the alarm sound emitted by the device to easily find them.”
A Bluetooth tag does not tell you where an animal is; it tells you where a phone last saw it. Indoors, that is a room at best. A speaker turns a vague position into a findable one, and neither of the two F18B listings on this page has one.
It works inside Bluetooth range, which is where an indoor cat is.
Bullet one: “No App & No Monthly Fee — simply pair the pet tracker with your iPhone… via Bluetooth.”
Bullet two: “get accurate global real-time positioning directly in the app.”
Both cannot be true. A Find My tag has no SIM, no satellite receiver and no radio of its own beyond Bluetooth: it is found when some stranger’s iPhone passes within a few meters and relays the encounter. In a city that can be minutes; in open country it may be never. “Global” is the size of Apple’s network, not the reach of this device.
The “7-day movement history” has the same limit: it records the sightings, not the route.
“Not only for pets, but also for cars, bikes, backpacks, and even children and the elderly.”
A device that reports only when an unrelated iPhone walks past is not a way to locate a person who needs locating. Judge it as what the first bullet describes — a tag for finding a collar.
No weight, no Bluetooth range, no battery type, and no explanation of how “global real-time positioning” is achieved. Twelve months is given as standby, which is not the same as twelve months of use.

No. It is a Bluetooth tag on the Apple Find My network: it carries no SIM and no satellite receiver, and its position is whatever an iPhone last reported when it passed nearby. The listing says so in its first bullet and then contradicts it in the second. In a dense town the sightings come often; across a field they may not come at all. For a position that does not depend on strangers’ phones, the shelf has cellular trackers — the Life360 and Tractive units published here.
It is the difference between knowing an animal is in the house and finding the collar. A Bluetooth tag resolves to a room at best; sounding the speaker from the phone and walking towards the beep resolves it to a sofa. Neither of the two F18B tags on this page offers it, and at $22.99 this one costs no more than they do.
Because it is the same OEM tag. Nilone sells it as "F 18B", SxingUxing as "F18B", Focushine as "F18A". The hardware differences between A and B are not published; the published differences are the speaker, the water rating and the price. Compare those three, not the brand names.
