Title: Great Price for Safety
Review: Purchased three of these a week ago to replace old smoke-only alarm w/9-volt battery. The AA-battery is a big plus, since this size is almost universal in electronic devices. Installation was easy, however, there was a discrepancy on which screw holes to use for mounting, but this was rectified with a call to customer service.(Mount as shown on p. #15 of instruction book.) Also, you do NOT have to use tamper-resistant feature to install. (This option is for use in public areas, access by children etc.) Product-life is two (2) years greater than comparable First Alert model & it has an LED light showing it's "working properly" [not available on First Alert.]If you're a NY State resident, it is now a law that homes w/fuel-burning furnaces etc. must have a CO alarm. This combo alarm is the answer.
