isn't it ok?

Blunt, truth:
NO! It's NOT ok. Those are not reliable at best, and last only a few days after installed, plus once they detect (If ever they do) it's too late and not reuseable. Trash it..... It was trash when you bought it.

I have to seriously agree with George on this one. Those spots are not good to have and are not reliable.

I had one in my plane just after I bought it and flew it up here. Ultimately, it seemed a little "less orange". I bought a Sensorcon, since we were using them in the Fire Department, and it immediately showed levels of 170 to 180 when in descent to landing, and about 80 or more in cruise.

The orange spot did not turn dark, just enough "less orange" to make me concerned/interested in levels. The Sensorcon CO detector is how we found the missing manifold bolt that had been missed on the pre-purchase annual, or it became missing within that first few months more likely.

ANY good digital CO detector is one you want in your aircraft.
