Would Recommend

Had a power outage due to high winds and ordered this from Lowes online, as it was the last of its kind in stock. Got it up and running about 10 minutes after pickup, and got my 2 fridges and upright freezer up and running on it asap, as it had been 8 hrs without power. Next up got the Mesh network up and running and then the 85" in the living room.
