Question: Is the "warm" setting low enough to keep already-cooked foods warm without cooking them further? Thanks!
Document: Without the pots it weighs about 2 lbs. Each pot has a spoon slot that would be nice if it were just a server but is useless as a crock pot as all heat will escape from the holes. There is no way to close it for cooking meaning your food  will take twice as long to cook. Save yourself a time consuming money wasting headache and pay the less than $20 more and get the REAL Crock Pot triple cooker which is what I plan to do once I get this unit sent back.
I do not cook from scratch  I  do cook my daily meals ( busy work and school)week For instance yesterday  8am I put boneless ribs in crock @ a low5pm  came homethey were done  all i had to do was make the side dish (mashed potatoes) I have made other meals  I have no complaints  I also use this for Family gathering to keep food warm so  i am able to enjoy family and friends
Great for heating up food for my xmas party!!! I've only used it in the low option. Easy to clean. I bought two.
I thought this would be great for cooking multiple dishes at the same time. too slow, takes forever. will use it as a warmer for company. Takes up a lot of space.
I bought this for my dad for Father's Day and he loved it. He is really into cooking and we used this item right away. A bit larger than we anticipated the product being but still so great! Affordable and shipped quickly! A++
I like to through parties time to time and I love to make a lot of hot foods for my friends. It is simple to use and the heating temperatures are not bad when using them.
Everything I needed for my large Thanksgiving crowd. Perfect for keeping sides or gravy hot. Also, work great as a mini-slow cooker (each of three pots has its own controls). I wouldn't be without it now. Hopefully it will make it through many family events.
I bought this for a party i threw, it was perfect it kept my beans rice and meat warm throught the whole party and left the meat super pull apart soft!kind of bulky but just the right size for a party of 20 drunk piggies lolwaaay better than the cheap aluminum foil warmers
Box came damaged and was just thrown in my yard in the snow (ups to blame for that I know) but it was supposed to be free shipping and it wasn't. I paid $30 for shipping and to top it off the stupid thing doesn't hardly work. Takes FOREVER to heat up, talking over an hour to melt a few small pieces of cheese. Stays warm when it does finally heat up, however it doesn't get hot. I hate this thing. It was purchased as a gift for my mother and it was a waste of money.
we used it for a partys threw the Holidays it worked out great I will use for all my next party's
Answer: The 'warm' setting barely keeps already warm food warm.  The 'low' setting has a bit more heat ... which can be used for overnight slow cooking.  The 'high' setting heats up the crocks fairly quickly, which I find useful for directly heating up canned veggies etc. just prior to a buffet dinner.  Also, unlike the unit mentioned by Cynthia, the base of the Nostalgia unit remains cool to the touch regardless of what heat setting it's on.
