I've only been able to use it twice so far, but it went swimmingly both times. I used it in a 12 qt. Cambro for salmon and chicken. I actually underestimated the size of the Sansaire, which I think people have mentioned has the largest footprint in its class. I tried to set it up in a Le Creuset 9qt dutch oven, but in a container that size, there is barely enough space for the food. Relative to the Sous Vide Supreme, the Sansaire heated the water much more quickly. Not necessarily an apples-to-apples comparison, as I was able to use less water w/ the Sansaire. I imagine the circulation of the water helps the heating speed. The strength of the water circulator is quite strong, and in the cambro container, the pressure is being blasted straight into the food. I don't know if that will have any effect on the result. Moving from the SVS, ease of use in the controls, ease of use in its portability, speed, and better accuracy all leave me as a happy camper. I've only used it for short lengths. Over the weekend, I'll use the Sansaire in a 48-hour cook and report back.
