"I Saw 47 PPM. My Old Detector? Silent."

“We had a detector that had supposedly been working for six years. The light stayed green, and it passed every test. I bought a Fortiva as an extra precaution—and on the very first night, it detected 47 PPM in my son’s bedroom. The old detector was still showing green and hadn’t made a sound. I unplugged it immediately. Fortiva gave me a warning I never knew I needed.”

"Nan's House Is Safe Again!"

“When my daughter brings the grandkids over for the weekend, I can finally relax knowing they’re safe in my home. As a nan, keeping my family protected is everything to me. Sentinel has given me that peace of mind again. Grandma’s house feels safer than ever.”

"I Sent One to My Mum"

“I bought one for our home and sent two to my parents. My mum is 74 and lives alone, so I wanted the extra peace of mind. Her old detector was over 12 years old—the sensor had stopped working, but the green light still made it look fine. Now I can finally sleep without worrying about whether she’s safe. Honestly, one of the best decisions I’ve made.”
