Well, I did a comparison about a year ago between Natasha and Pipenet TM. Here I must say that I was not totally impartial, since I was already familiar with Pipenet TM, but here are some of my conclusions:
- possibilities within Natasha are more limited within Natasha than in Pipenet: shape of pump and valve curves, units to be used (for example, for pressure you can only choose Pascal or PSI, not bars), less equipment that can be selected
- input of pump and valve curves seems difficult in Natasha
On the other hand Natasha is also cheaper than Pipenet TM...
