With adaptive images mobile users load only 14% of desktop data
With adaptive image we were able to decrease amount of transferred data to 14% from desktop view. So mobile browsers even with low speed are able to have good browsing experience.
Size of all images without adaptivity in desktop view is 1,2MBytes.

Size of images with adaptivity in mobile view is 0,17MBytes.

So if you are making really visual (lots of images) website with responsive design you should really consider adaptive images. There’s no use of responsive design and mobile view if loading a mobile page takes forever.
