Super alternative to smoke detectors in the living room

Application:
I use this heat detector only acceptable in the living room or in our open kitchen. Due searing and the smoke from the stove, there was often a false alarm of the previously mounted smoke detector.
This was already talking with little smoke immediately and bugged us sometime. I then read me something and came across this alternative rather than the heat reacts to smoke.

So far, after more than a year he has triggered no false alarms.

Why this product ?:
I think the price is low and heat detectors, there is not as much choice as in smoke detectors. In addition, the good recessions have me convinced.

Processing:
The heat detector is made of plastic as well as all smoke detectors and in my opinion is processed normally.

Significance:
The product makes a normal impression neither especial quality yet cheap.

Price-Performance:
I think the p / l ratio is good, because I did not want to spend more than 10 for a smoke or heat detector and he needs me even the many features have the expensive models often.

Criticisms:
Unfortunately, not really white but rather beige but not leading to withdrawal.

Conclusion:
I would buy the heat detector again since I'm convincing by the quality.
