I purchased this product because of the good reviews and the brand name, and I liked the idea of controlling through WiFi. But, I had to return the first unit, after I hooked it up to the WiFi that I wanted. Was working perfectly until I hooked up the WiFi. Once I replaced with the same unit and didn't hook it up to WiFi. It wasn't glitchy and worked perfect. For some reason after hooking it up to control with the app, it wouldn't work right, at all. I don't know if it was the one I originally had or something else. But I just used the replacement air conditioner with the remote. And didn't have any more issues after. Hope this helps someone!?
