Customizr Slider Image problem on mobile

Hi Friends,

I’ve installed customizr theme which is really a great theme. However, when I’m adding sliders images show properly on my laptop but get cropped when i see from mobile. I believe customizr is a responsive theme and should be able to take care of it but does not look like.

My website address is http://pmsitsolutions.com/information-technology/laptops/

Here the slider images look fine but when i view the same page on mobile, the image sizes are getting cut.
