Review: Great product! - Works perfect! Great product! Made in the USA!
Review: They saved the lives of my babies. - I am very emotional as I write this review. Charlie and the other representative worked with me for a very long time and were so patient. The first unit did not work. We went through everything. They were absolutely amazing. Their help was personalized, kind, friendly, everything you could hope for. It was determined the unit should be switched for another one. It was perfect. After finishing all of my testing, only a few days passed, and then today arrived… I rushed home as fast as I could and because of their customer service and truly, truly caring, and sticking with me, my cats are alive. If they had given up on me, my babies would be gone. One has very long fur and special health needs. He has to be cool. Please see the photo attached. This is inside of an RV sitting on a concrete slab in the Texas sun. Outside it was 97°. Thank you, thank you. And my Libby and Jackson are alright. Two lives were saved.

### ⭐⭐⭐⭐⭐ Excellent Monitor and Service - Well Worth it for Peace of Mind
*by J***R on March 19, 2026*

I have had this device for several years now to monitor a cottage in Michigan. It has performed perfectly keeping track of temperature, humidity, and power. I can connect from anywhere and often check the monitor on my iPhone. Because it uses cell service, there is an annual fee, which I find is well worth it. The monitor itself has always lasted longer than any power outages - I had one for nearly 24 hours and the marcell pro was still reporting status. Plus, when the power comes back on, the marcel monitor recharges. My old monitor would wipe out the batteries in a few hours with no one around to replace them. Use of cell service makes this monitor independent of internet service, which often goes out especially when there are power outages. The unit also keeps histories, which is good for spotting trends and comparing what is normal or not-normal. Lastly, active monitoring helps with insurance companies, especially because you will know to call in help to quickly to fix problems before they grow into serious damage.
