Review on Enhance Safety with Safe-T-Alert 35-742-BR Dual LP/CO Alarm - Flush Mount, Brown by Duane Kaul

The detector is a must. I think it's even a legal requirement in RVs. Mine started beeping regularly a while ago (and always at 2am). I removed the old one, took the model number from it and ordered another one. Interestingly the sticker on the back said they needed to be replaced every 5 years (this one had just over 5 years) right? Easy to connect, just match wire to wire. If I have any complaints it is that this item is a little pricey but is necessary for safety reasons.
