Personal Calculation

Do you know about personalization trend in UX?
I made this work based on this.

It's personal calculate. Made for internet provider company. Often many company use different plans or tarrifs for their client's.

We deiced to give our user's personal choice and opportunity to adjust all parameters and make their own plan. You can choose how many days, what kind of options, and how much it all costs.
In really you can choose from 1 day to 2 years.
