Not what I expected
I was excited to replace the sensor in my 2009 Mazda 3, but unfortunately, this one didn’t work right after installation. I double-checked the compatibility, and it matched, so I’m not sure what went wrong. Disappointed with this purchase.

Came with minor flaws
The sensor for my 2011 Mazda 2 arrived with a slightly bent connector, but it still worked after I straightened it out. The performance seems okay so far, but I had hoped for better packaging to avoid this issue.
