Kajabi ecommerce platform

Has anyone heard of, or used, Kajabi (https://kajabi.com/) one of my clients is thinking about moving to this platform and I just want to know what peoples thoughts are of it.

Its basically an all-in-one platform for selling courses online - a bit like Shopify I suppose, but for course based products and services.

The alternative would be wordpress and woocommerce but with kajabi it seems that you get everything bundled in - ecommerce, website, marketing etc.

Thoughts?

I prefer Magento for eCommerce, but depending on your client products it might be a good solution
