Hi all....

I'm in need on a CO detector for home use

I'm seeing many combo CO detectors....either a combo CO
and smoke.... or combo CO and natural gas unit.

Is there any value to buy such a combo unit or is it
best to have sep units for each function?

If combo units are good thing..... WHICH combo model?
the CO and smoke.... or CO and natural gas?

It is my understandng that the combo units aren't nearly as good as
smoke rises and CO sinks. Putting a smoke detector low won't do much
good, nor would a CO do much good high.
