CO/LP Detector replacement recommendations

[txpedsrt]

So, mine would not stop beeping after 1 week of being plugged in at my home. 31 series battery was fully charged and it was plugged into shore line. I have only had this camper for 13 months but I need to replace it. It came with a MTI 25 series, but I am looking for other companies that might make a better product, so any recommendations you can make will be helpful.

the age on your rig has no bearing on the age on your Co detector they put in what is received from the vendor who knows how old that stock was

I understand that, and mine was manufactured sep. 13, 2016. That is why I I am looking for recommendations for something that has better reviews
