UPDATE: Reports of difficulty connecting to phone Bluetooth are accurate. Biggest tip is use the QZsmart app (scanning the QR code was problematic for me as reader kept going to wrong app while searching android play store didn't find the app either) and be on a 2.4Gz network with your phone (also problematic as I forget my 2.4G extender password). But once resolved setup was fairly easy. The app is intuitive and biggest advantage is being able to monitor the cooler while driving to make sure it is working properly in in the cargo area where you can't just glance at it. Otherwise, you might get an unwelcome surprise when you stop somewhere only to find out the cooler was not working.I tested the cooler immediately after delivery with the assumption that the cooler was only transported in the upright position, so maybe these test results are skewed if the refrigerant needs to settle.After 30 minutes on house power: The refrigerator section reached the set temperature of 40 degrees (per the led indicator), although the bottle of water inside only felt cool, not cold. The freezer section reached an indicated 33 degrees of the set temperature of 20 degrees. The bottle of water inside was only cool and no where near freezing.After 60 minutes on house power: The refrigerator section maintained the set temperature of 40 degrees and the bottle of water inside felt chilled enough for a refreshingly cool drink. The freezer section reached the 20 degree set temperature. The bottle of water inside was chilled but still along way from starting to freeze.Moved cooler to idling Tacoma truck bed and plugged into the 110V 400W Max / 100W Min bed outlet. After additional 30 minutes (90 mins total) the cooler display read 40/30 degrees. The outside temperature was 80 degrees and the truck was idling in the sun with cab A/C running. The truck bed has a BakFlip4 cover so the cooler was not in direct sunlight. I'm guessing that at driving speeds the outlet would produce higher watts and the cooler would do better.Moved cooler to idling RAV4 and plugged into 12V/120W cargo outlet for another 30 minutes. The outside temperature was 80 degrees and the RAV was idling in the sun with A/C running. After 30 minutes the temperature was 40/20 degrees. Interesting that the cooler did better with RAV4 12V/120W outlet at idle than the Tacoma 110V bed outlet at idle. Maybe due to cargo area getting A/C benefit.Both bottles of water were very chilled at the end of two hours. The water in the freezer was nowhere near freezing but maybe a little colder than the bottle in the refrigerator side. Guessing that freezing will take 5 to 6+ hours. When camping it will run on a 3500W generator or shore power. No error codes were ever thrown. Overall I'm satisfied. If this cooler operates well for years it will be worth the money.
