    "We bought this for our RV before a two-week trip and I’m so glad we did. On the third night, the alarm went off for natural gas — turned out there was a small propane leak from the stove fitting. We aired it out and fixed it right away. Without this, we would’ve slept through it. Compact, easy to read, and worth every penny."

    "I thought our old CO detector was enough until I read it didn’t detect gas leaks. This one covers both, plus shows temperature and humidity. Super easy to set up — just plugged it in by the kitchen and it started showing readings instantly. Gives me peace of mind knowing my kids are safe."

    "Very clear screen and loud alarm. I tested it with a small burst from a lighter and it detected gas immediately. Only reason for 4 stars instead of 5 is I wish it had a battery backup for power outages. Still, for the price, it’s excellent protection and I’ve already bought a second for my garage."

      Will this actually protect me better than the detector I already have — or is it just more “features”?

      ✅ Yes — and it’s not even close.

      The Protmex 4-in-1 uses high-precision sensors to monitor carbon monoxide, natural gas, and propane — plus temperature and humidity — in real time. Most detectors only cover one gas, with no extra data. Ours gives you broader protection, faster alerts, and clear readings you can see at a glance. Extra features aren’t fluff — they’re more ways to keep you safe.

      I already have detectors at home… why would I switch?

      ✅ Because your current setup might not cover all the risks.

      Many homes only have CO alarms, leaving you vulnerable to gas leaks — or they rely on hard-to-read units tucked away in one room. Protmex covers both CO and combustible gases in one device, works anywhere you have an outlet, and is portable for travel. One plug-in and you’re protected in bedrooms, kitchens, RVs, hotels — wherever you are.

      Can I trust this to work when it matters most?

      ✅ Absolutely — and here’s why.

      The Protmex uses proven sensor technology and gives both visual and audible alerts (85 dB) the moment danger is detected. Color-coded lights and a live LCD display keep you informed before it becomes critical. It’s built for 24/7 monitoring, so you’re never guessing — and never left unprotected.
