Easy to use assemble and a good price with winter fast approaching and safety being a priority in my house i invested in this purely because everyone is talking about the silent killer carbon monoxide poisoning for me this this can be attached to a wall and is very easy to read and lets you know if anything is wrong so everyone needs at least in or two of these in there house

Oh plus gas check i dont think a lot of people bother nice carbon monoxide alarm with an lcd displayseems to be working great
