Yes, 3M does manufacture the device. The Pro Tech logo that you see on the device is my old company, and we're still in the process of transitioning the branding over from Pro Tech to 3M, but this is a 3M device and 3M is now the original equipment manufacturer of this device. They own all the IP, all the design, and 3M does all of the manufacturing, all of the support development, and what not.
