Don't base a child theme on it

Don’t try to use a child theme with this one–their CSS/HTML is terribly written. It has way too many IDs, the CSS specificity is over-specific making any kind of inheritance based on their styling frustrating, and the grid system they use for responsive design is strage and hard to work with. If you want to use this theme out of the box with little to no changes, I’m sure its great, but avoid it as a parent theme that you’re basing your child theme off of.
