Query: Alarm triggers with steam, but not smoke?

Absolutely useless. Whenever someone is taking a shower, the steam from the bathroom sets off the alarm in the hall 15 feet away. Heaven forbid I boil water on the stove 15 feet from the downstairs alarm--the steam strikes again! I've begun taking the battery out while cooking or showering, which is a pain in the neck. And based on the other reviews, when there really *is* smoke nearby, nothing happens.
