The Quadrat Register 11 can be purchased at qreg.tech. This is a new product from the company that produced one of the best performing devices to date; the Quadrat Register P. The P version was more complex with a lot of loose parts while this version is a much simpler “sandwich.” They don’t make durability claims.
This device has a novel encoding system. Novelty can be bad; if you’re trying to recover data and don’t know how to decode it, you’re gonna have a bad time. I ran it by a Bitcoiner who is less technical and they were not a fan.
Actually setting up the device is a bit trickier than a center punch; qreq provides a tool to punch out the squares from the plate. Once you get the hang of it, it takes 5 to 10 seconds per square.
Heat Stress Test
I had a really hard time reopening this device. In fact, the supplied wrench sheared off and I had to go find a sturdier wrench with a security star head. Some commenters have said this could be a result of using titanium screws in titanium plates. “Titanium galls with itself and steel fasteners will galvanically corrode over time if mixed with titanium. It’s a dilemma.”
That said, once I got the device open it was in pristine condition.
Corrosion Stress Test
No data loss.
Crush Stress Test
Similar to the original Quadrat Register cylinder, my press was unable to visibly deform this device. No data loss.
