Review on 📊 Stay Connected with MarCELL PRO Cellular Monitoring System (Verizon): Ensure Ultimate Protection and Peace of Mind by Sean Ceo

I have a building with multiple plumbing and a heater. The heater broke a few weeks ago and our plumbing froze causing a real mess. After the heater overhaul we bought and installed this Marcel Pro which gives you peace of mind knowing you will get an alert at whatever thresholds you set. Reason for 4 stars instead of 5: $179 annual subscription, no price reduction when used. multiple devices, each costing $179. Although you get an instant notification when an alarm occurs, the device takes readings every 30 minutes but uploads them to the web server every 6-12 hours. If you're paranoid like me, you'd better upload data more often. Of course there is a button to get the current conditions, but it is limited to 40 manual extractions and 20 are added every month.
