5 Stars
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.
Thank you for your feedback
