A camera at each brow corner, and a light that tells everybody when they run.

The awkward questions.

It passed ISO 12870 at fourteen grams — the same tests every frame sold in the EU has to survive. The lattice is why: hollow where the load never goes, solid where it does.

No, and we won't pretend otherwise. A rigid frame needs an industrial composter and nine to twelve months. Send it back to us instead and take 15% off your next one.

Yes. A light on the outside of the brow is wired to the cameras and can't be switched off in software. Light off means nothing is being recorded.

We never bought a mould, booked a factory minimum, or filled a container with stock that might not sell. That gap is the whole discount.

Thirty days. The frame goes to the composter, the Core goes back on the shelf, so a return costs us a frame rather than a pair.

The awkward questions.

The ones people actually ask us in the shop, answered the way we answer them there.

It passed ISO 12870 at fourteen grams — the same lens retention, bridge and endurance tests every frame sold in the EU has to survive. The lattice is why: hollow where the load never goes, solid where it does.

IPX4, so rain and sweat are fine, but don’t swim in them. PHA holds its shape to 60°C: a hot dashboard is survivable, a sauna is not.

No, and we are not going to pretend otherwise. EN 13432 was written for packaging film; a rigid frame needs an industrial composter and nine to twelve months. Send it back to us instead and take 15% off your next one.

The frame does. The Core — cameras, board, cell, display engine — is built to outlive several frames, and comes back to us to be stripped for parts when it finally dies.

Yes. A light on the outside of the brow is wired to the cameras and can’t be switched off in software. Light off means nothing is being recorded.

To your phone over Bluetooth LE, and nowhere else unless you send them somewhere. There is no cloud account, and nothing on board recognises faces.

We never bought a mould, never booked a factory minimum, and never filled a container with stock that might not sell. That gap is the whole discount. The optics and the silicon cost us what they cost everybody.

Thirty days. The frame goes to the composter, the Core goes back on the shelf, so a return costs us a frame rather than a pair.
