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

We used Marcell during our 10 day pet trip. This was accurate for the temperature and immediately sends an alert if the temperature is out of range. It ran successfully for over 24 hours on battery power. The disadvantages are 1) it must be connected to the mains for the first operation, even with a fully charged battery. It is inconvenient when you need to control the temperature of the car and the device is turned off. 2) When sending a notification, e.g. B. "Temperature out of range", you will not get the corresponding text that the temperature has returned to the normal range. I don't want to spend an instant update just to check the status. Not entirely satisfied and not dissatisfied enough to return it, but not what I thought it would be. In the modern world, technology is not enough here.
