I tried to use NB for smoothies also tried for baby puree it worked for both. On hard products as the soft also. liked how it worked its too easy to use. It has two tipe of heads one with blender and second just cup head which one has its hole for straw which one is also included and also container dont know who will use for what. Head with blender is a little bit heavy. One thing what i didnt liked was that it is a little bit hard to clean.
