This product
appears to be the only one of its kind that does not require a
password and, as such, cannot be removed at will. It also
appears to be
easily accessed over the internet,
covers every site associated with gambling (including those
developed after the installation of GamBlock), and can be
downloaded and implemented by a partner without the gamblers
consent. The cost appears to start at $US40 for a 12 month
licence.
