Did Anyone use the Witourist pocket wifi service in Florence?

In October I will spend a week in Florence and around Tuscany.
I found an interesting mobile wifi service for all my family: www.witourist.com
Did somebody use it?
I was looking for an Italian sim card but I understood that often the sims are locked for being used in hotspot mode...an expensive overcharge is required.
Waiting for your replies.
