Excellent but for the responsive behaviour

I am using the free version of this theme on a buddypress site and it delivers on all of its promises save one, it is not responsive.

I’m trying a new type of site out and I want to test the concept before spending money. Thus far x2 has been the only free theme that allowed me to create a look professional enough to let users feel comfortable with the alpha site that they are using.

It’s just a pity that it isn’t responsive as promised.
