iPhone Duo 512 GB Star White
MATT: The robot behind the Revendo Quality Label
Our new colleague: Robot MATT
Since this summer, a very special team member has been supporting us at our Basel headquarters: MATT.
The diagnostic robot thoroughly tests every used smartphone - from the camera to the battery. And because it repeats every process with millimeter precision, it delivers reliable, objective results.
That’s not only pretty impressive, but also a real milestone: Revendo is the first company in Switzerland to use automated testing in day-to-day operations.
A label you can trust
But that’s not all: Every device tested by MATT and our team gets its own Revendo quality label.
With a QR code, you can see exactly how your smartphone performed in the test. This makes transparent what is often only promised: genuine quality.
Old devices, new opportunities
While others forget their old phones in a drawer, we give them a second life - tested, repaired, and with complete transparency.
Because with innovation, a little Swiss pioneering spirit, and a robot named MATT, we’re showing that Used is the new New.
