What to know before buying

Listing details to confirm

Listing details are inconsistent: the title identifies a 3-pack and the specifications say three items, while the listing also reports one count and one pack. The Bluetooth range is given as 262 feet in one listing highlight and 250ft / 76‑meter in the feature text. Confirm the selected listing's bundle and range details before buying. The up-to-24-month operating-time claim is not accompanied by specific lighting or usage conditions, and the listing provides no numerical measurement-accuracy specification.

The supplied rating data is uniformly positive, but the sample is very small and there is no written customer feedback to explain the ratings. It cannot establish how well the app alerts, Bluetooth range or light-assisted operation perform in everyday use.
