Licencias algo costosas?

The statement is incorrect or not true.

Thanks for your honest answer, but wouldn't you sleep better if you pay for a license? I guess you make money with your services, that's why I pay as well, its a lot, I agree, but using it daily and no downtime, its worth it.

Yes, the licenses seem too expensive to me, generally I use the free service which gives me time slots that are wide enough to resolve my clients' questions.

You may logon to your teamviewer account on the teamviewer website to manage your licenses, there you will see an overview of available licenses, used licenses and you may upgrade from there.
