Customer Satisfaction Survey and Feedback Anonymously
Please help us to develop RheoPower Software Package by completing this short survey.
We will use your feedback to determine how we can improve our future software versions.
Confidently and Anonymously
Filling of this form can be done anonymously. Your identification information or email address are not required.
The only identification information we can see later on, is the IP address of the computer your web browser is on.
As there are many dozen visitors daily on our web pages it is nearly impossible to identify the sender.
We promise not to use that information to track you down, but if you are really concerned about anonymity,
you should consider submitting your comments from a public computer.

Purpose of this Survey
Using your valuable time for few minutes may helps a lot developments for rheology, polymer analyses,
viscoelastic properties and understanding more microstructures of macromolecules in future.
