I bought many of these for Christmas gifts this year. I even bought one for myself. It keeps food plenty warm and is the perfect size. Only complaint is the lime and grey is definitely not lime. It's very yellow like banana yellow. No hint of lime green whatsoever. That was very disappointing considering I bought a few in that color because some of my family's favorite color is lime green. The red and the blue ones are true to color though!
I prepped all my ingredients the weekend before, plugged in the cooker first thing when I got to work, had it going for 4 hours and the food wasn't quite done yet. I think it's better as a reheating tool rather than a full cooker. Or if you have more than 4 hours to wait for lunch, it's great! Just a bit of a warning as it does not cook as fast as the big cookers. Other than that I love it. It could be a bit bigger but for me it's plenty.
I bought this and used it every single day after I bought it. I LOVED it. Then hurricane Harvey hit the area and flooded the entire town destroying it. We lost everything, but I MISS MY CROCKPOTS!!!!
