Amazon.com has the Leeo Smart Alert Smoke/CO Remote Alarm Monitor for iOS and Android for $29.15.
The only other times it has been this cheap was in November for $25 and January for $28 where it was a front page deal and sold out the same day both times. This item does not seem to price drop that frequently and I have been eyeing one for less than retail ($50). A few dollars more than lowest but figured some people may want to know.
This is a smart listening device – not an alarm itself. It listens for your other alarms (smoke, water, co2) and notifies you through alerts and calls
