Has anyone used DENSO O2 sensors?

I have a code for downtstream, and thinking about buying those two for now. Denso makes our a/c compressors, so it's probably safe.

The materials used appear better than most; stainless steel. $64 at Rock Auto.

DENSO-
Porous PTFE Filter - Allows atmospheric oxygen to enter the sensor without permitting water or engine contaminants to seep into the casing.
Robotic Laser Weld
Aluminum-Oxide Trap Layer - Keeps silicone and lead outside the ceramic elient through DENSO's exclusive design, preventing damage to the platinum electrode.
Stainless Steel Housing - Resists corrosion and contamination with a rugged, watertight body.
Double Protection Cover - Maintains proper unit temperature for quicker response times and protects the ceramic element against silicone and lead poisoning.
