Netshield works well for the most part but it does not block as many ad networks as I would have anticipated. Some mobile games still show ads when being played while Netshield is enabled. I understand the usability aspect of things need to work, it would be beneficial to offer different levels of blocking so we could adjust the service to or liking or standards. This could be done by offering different levels like standard, advanced, adult, family or custom block lists that are supported through the app.
