    Upgraded with perfect fit

    Our old Safe-T monitor just detected propane gas leaks, but wanted to upgrade to include a CO2 detector for just a few dollars more. This was a very simple process - just removed the old screws and disconnected the 2 wires. The new monitor fit/aligned perfectly in the old hole, including the 2 screw holes - no adjustments needed.

    Bought as a replacement

    Bought this as a replacement. Why do these need to be replaced is poor electronics. Shipper was good, came quick, easy to replace expired model. Seams to work fine. No complaints with the eBay store I bought it from. But I do thing the manufacturer of this product is poor quality.

  • Safety-T-Alert Detector Recommendation

    Not the cheapest, worth the investment. This detector replaces the same model reaching its end of life as recorded, 5 years. The original lasted 6 years. Recommend this Safe-T-Alert detector for your RV. I installed in 2015 Tiffin Phaeton.

  • Perfect Fit

    Replacement was a perfect fit and literally takes no more than 5 minutes to swap out. The only con to this item is the price. My opinion is that it is way over priced. Would have seriously thought about not replacing if I didn't have kids sleeping in the RV. Good value for its safety function, poor value for what it costs.
