Co2 detector

[montara24d]

Having problems with the CO2 alarm in the 5th wheel, & shopping for a new one. A battery powered unit in the camping store is on the average of $75. A battery powered unit in the local big box store is $17. for a KIDDIE, or $18. for a FIRST ALERT, both name brands. Are they the same? Do I need the RV specific unit?

Did a quick check of Consumer Reports and they contended that all the carbon monoxide (CO) detectors they checked worked, some just faster then others. All have a life span of some 6 years or so. So other then profit margins differences the more expensive the faster response time but cannot say if that is buying decision.
