Hello,
After shopping around much, purchased a nighthawk digital for $33 from
wal-mart.
These are expensive and I'm wondering if the best placement would
be high in the hallway near the bedrooms. There are 3 bedrooms that are
occupied.

Is this a good idea?

Should it be directly under a vent?

Thanks much!

Hmmm,
$33.00 is expensive which may save your or yours' life sosmeday?
