You can choose to exclude tablets from using the mobile version of the site built with Responsivizer.

However when you turn off tablets inclusion if you have already visited the site it could be the case that on your tablet you will continue to see the mobile site.

This happens because of a cookie that is used by Responsivizer. In this case simply clear cookie or browser cache on your tablet. After reloading you will be sure that tablets are really excluded and will continue to show the standard desktop version of your site.

In most cases is not a good idea exclude tablets from the mobile version of the site. Tablets exist of different screen size and resolution and a responsive site better adapts to their requirements.
