I have only purchased one DÃ¶rr product and it was completely unintentional. I ordered a Lenspen Sensorklear sensor cleaning pen. When I opened the box and saw a DÃ¶rr Sensor Klear package I was disappointed until I actually looked at the pen through the clear plastic. It is a Lenspen product packaged in the DÃ¶rr packaging. The pen itself has Lenspen printed on it and not DÃ¶rr. So, I imagine that other DÃ¶rr products are repackaged items from other manufacturers. I would inspect the DÃ¶rr filter to see if it has any manufacturer's info on it before making a decision on it.
