Review on Kidde 21026065 Smoke & Carbon Monoxide Alarm: Voice Warning for Ultimate Safety by Kari Barley

I moved into my apartment and had this combination smoke and carbon monoxide alarm. One day my nephew came to visit me and accidentally hit him and destroyed him. So I just bought one as I already have the wall mount installed on the wall. When I received the new replacement, the packaging had already been cut and opened. hmmmm It looks like one of those packages that someone bought, opened, and returned. then they sent me this opened package. I haven't returned. I clicked the check button and it seems to be working, so why bother. But I feel like this order left a bad taste in my mouth.
