Quality and reliability is essential. We buy direct from the manufacturer, the same manufacturer that provided the same beacons to Google for Google I/O 2016 and their offices. Our Eddystone beacons are fully secure enterprise-grade quality.
Really want to know the technical details?
Our beacons transmit signals up to 100 yards, are powered by a single CR2477 battery that lasts up to 2 years (at default settings), is IP66 weatherproof... and has an on/off switch. (Not all do.)
Wondering how small the beacons are? They are 2 inches around and weigh less than 1 ounce.
And if one ever fails, we will replace it for FREE. (You are still responsible for the battery though.)
