This is my first cooler with compressor and I am very surprised by the performance. I used it for 4 days camping in the Hautes Gorges de la rivière Malbaie park in Quebec (we were 3 adults and the 45 L cooler was big enough for fresh food) with hot days and cooler nights. The temperature of the cooler was programmed at 3 Celsius and it kept our food in very good condition. The configuration is simple but I was not able to do the Wi-Fi connectivity which I do not find useful for me. The Bluetooth on the other hand works well to program the temperature of the cooler and there is a diagram to know the evolution of the internal temperature. I will not go back to a cooler with ice unless I have no choice. I used an ecoflow delta 2 max battery and 200 watt solar panels and I didn't run out of power at any time, but of course there was plenty of sun during the day. I recommend it for people who can afford the purchase despite the high price.
