Bests & Worsts Reviews from Amazon

I bought the 8 qt after doing a lot of research, but despite all my careful research there were some unexpected surprises. First, I was under the impression the only difference in the 6 and 8 was size. The 8 quart requires more water or liquid to reach pressure (2-2.5 cups vs. the 1-1.5 cups for the 6 qt)-- this can affect many recipes that call for only 1 cup of liquid! The 8 qt is really for cooking larger quantities, but I thought I could cook smaller portions in it too, and you can but, again, you have to add more liquid than some recipes require. You can get around this by doing PIP (pot in pot) cooking, but what a hassle if you want to sear or sauté something--you would have to do that in the inner pot, then transfer everything to the PIP smaller pot (which you have to figure out what to use and buy it), you can then add the amount of liquid to your dish, and if it is not 2 cups, then you would add 1 cup of water to the inner pot itself, so, combined you have enough liquids to reach pressure. The 8 qt, because it holds more, takes longer to release pressure naturally (and maybe a little longer with quick release, too). It is a wonderful size, and I thought it would be versatile, allowing me to cook large or small portions, but I am cooking for two and this is just too big since it requires the extra liquid. I exchanged it for a Duo60 without doing anything more than the Pressure Test. Please note, I spoke with customer service at Instant Pot because the Manual says the Pressure Test natural release time would be 15 minutes and it took 55! They said the manual has a misprint, the "3 mark" should read 3rd mark, not the number 3 because the 3 is 3 liters and the 3rd Mark is 3 cups, so yes, big difference. I thought the pot was defective, so was glad I called. Very nice people!! I gave the 8qt 4 stars because it is a wonderful appliance, the -1 star was for not explaining the differences better so people can make a more informed decision on which size to buy. Gotta love the ease of returns on Amazon,
