This unit was on sale for a great price, checked all the boxes, shipping was lightning fast, and customer support was fantastic. The unit itself was straightforward to install, and came pre-charged with refrigerant. (You'll need some specialty tools.) I purchased for my garage, and it's working champion. I was able to sync it with my smart home Alexa using the app. This is a great unit, and cools down my garage (About 1,000 square feet, 13 foot ceilings) in about 10-15 minutes. My only small complaint is that the remote is a little confusing to use and not very straightforward.
