Review: **Title: Exceptional Wireless Thermometer and Freezer Alarm - A Must-Have!** - **Title: Exceptional Wireless Thermometer and Freezer Alarm - A Must-Have!** I purchased the Marco MOCREO ST5 wireless thermometer and freezer alarm Hub in July 2024, along with its required hub, and I couldn't be happier with my decision! Setting it up was a breeze, and it seamlessly connected to our Wi-Fi, reaching an impressive distance of over 130 feet. In fact, we even tested one of the sensors in our car while parked, and it maintained a solid connection from the parking lot! As a pantry dedicated to helping feed the poor, ensuring the safety of our food is a top priority. These thermometers have been instrumental in keeping our supplies safe for our clients. I highly recommend them! The product is not only reliable but also user-friendly. We did encounter a minor issue where one of the sensors got unplugged, but the alarm system quickly alerted us with additional icons, allowing us to address the problem immediately. The ability to set temperature ranges and receive notifications if one of our freezers fails provides us with invaluable peace of mind. Customer support was quick and excellent, addressing our questions efficiently. The app is fantastic, giving us real-time access to the exact temperature of our freezers right on our phones. Overall, you can't go wrong with the Marco MOCREO ST5 and HUB. It's an outstanding product that offers peace of mind, making it essential for anyone needing to monitor temperature-sensitive items. Five stars all the way!
Review: Great warning system about freezer failure. - Great product. I no longer worry about a problem with a freezer or refrigerator failure without a warning that I have a problem. It has an audible alarm and it also sends me an email if the temperature goes above or below my preset temp range. I first bought the package set and then bought extra sending units for my other refrigerators and wine fridges.
