  1. James G

    My boat has a refrigerator and a tiny freezer that only goes to 26 which is pretty much just ice. I purchased this cooler and run it as a freezer at 7 degrees F. Very quiet and makes less sound than my refrigerator. You would have to stand less than a foot away to hear it. I downloaded the app and use Bluetooth to monitor all functions of my freezer on my phone. So far power consumption is almost zero. I have it on 110 V but underway (offshore) I will use 12V. Very happy with my purchase. I also have several Dometic products aboard and perform flawlessly, worth the extra money for excellence.

    I am in the process of converting my 2014 Honda Odyssey into a camper van. This unit, based upon size, quality, and functionality fits the bill perfectly. Probably a bit pricey, but the quality construction is obvious. Easy to remove this unit from the vehicle and set it on a picnic table when/if desired. Low noise, low power consumption, excellent temperature stability, and the biggest unit that my camper conversion would accommodate. The top of the unit makes a fine workspace or seat within the van.
