Bests & Worsts Reviews from Amazon

No question, it's sleeker. However, two big issues. First, it's clearly slower at heating the water. I had it side-by-side with it's big brother and the volume of water in the bigger container (with the older unit) actually heated faster than the smaller container (with the Nano). Both started with water the same temperature. Second, you can't adjust the depth as you can with the older model. That makes it much more selective on the height of the container you're cooking in. Finally it is smaller and sleeker than the older model but only marginally. The amount of storage space is really not improved dramatically. We love both of our Anova cookers, I just wouldn't buy this smaller version over the bigger one.
