Is it your website as well? If so, the mobile experience needs a few tweaks. Especially when viewed in portrait orientation.

The arrows to go back and forth are tiny, and very close to the slide window. Which, when your finger overlaps onto, jumps around and zooms. I thought maybe swiping would work, but it does not.

The top menu links are pretty tiny as well.

I thought it worth mentioning because the amount of work to fix it seems pretty low.
