Review on πŸ”₯ First Alert CO710: 10-Year Battery & Digital Temperature Display CO Detector by Jordan Perez

Revainrating 4 out of 5

It could be better. - Safety

What I like: Doesn't need to be plugged in, runs on a battery said to last 10 years. Just take a look. I can put it on a shelf instead of mounting it on the wall. If there is a dangerous CO value, it will be displayed. I hope. What I don't like: The CO value is only displayed if it is above a mysterious value. If the level is low or zero, it will not be displayed. If you try to display the CO level and it is low, the device switches to test mode. Very annoying! I don't need a room temperature display, I'd rather see the actual CO level even if it's zero.

Pros
  • Very good value for money
Cons
  • Reliability
