At the moment I have both the French Télépéage VINCI Autoroutes and the Italian Autostrada Telepass. Both now have validity in other countries such as Spain but the Italian Telepass can now be used in France, Spain, and Portugal.
The cost of use is a little higher than the French one (€2.50 as against €2.00 in the months that it is used outside Italy) but I don't think it makes a great deal of sense to have two devices that do pretty much the same thing. I more or less have to have the Italian one and it costs €1.26 a month for the basic service. I actually pay a little more for the premium service which gives me free roadside assistance if I need it.
For the French one it only costs me €2.00 in the months that I use it but if I don't use it for 14 months the charge is €10.00

Once I update my Italian one to the international version I will close the French one.

As far as mounting it is concerned I have a Velcro strap to hold whichever one I am using to the top of the sun visor.
