Verified Amazon reviews from owners who replaced an old detector with a SENSYX.
“I purchased the SENSYX as a replacement for my motorhome's 10-year-old Series 30, which would not stop beeping. Reassuring, especially when you're asleep or just hanging out.”
“I had a malfunctioning RV Safe propane detector that went off night and day. Power was fine, checked for propane leaks, none were found. The new model is perfection — no false alarms. I can sleep again!”
“On a camping trip mistakenly bumped up against the gas stove knob and turned the gas on. A few minutes later the alarm went off and alerted us. Worked as advertised.”
