One thing to keep in mind with coscto is that if your membership lapses, you lose all your warranties.So this is not the best fridge, but it seems to check more of your boxes than the NL which is very highly rated, and priced.
I've been using it for a few months, and it's great. Doesnt use much power in fridge mode. It takes a bit more power to keep it under 5f though. if anything does go wrong, I'm hauling it in to costco and getting a new one.
Even things like car batteries and tires. I had a 4 year battery that quit after two years but since my membership had expired , I was out of luck.
