Liked the solid feel ,ease of use and the fact our 120W solar panel on cloudy days was able to keep things cool over 4 warm days and not drain the 120AH battery too much.Very quick drop to set temperature on initial set up on AC supply at home. 23 to 3 deg C in 15 mins.Also we ran it overnights in camper van and it did not disturb any sleep. Soft shushing noise only.Didn’t like and needing a review the instruction was the fact we set to -6 for last two days but no freezing took place even trying Eco and Max settings.Generally happy with purchase but would be much happier if we could get it to freeze on DC.Very good value compared to others if it keeps going and gets stuff frozen when required.
