Haven't taken any of the class with them, but just an observation - they are pricey, and have a start and stop date. For me the joy of on-line classes is access when I want and not put on a schedule - hence, I love the Craftsy platform and other classes that provide unlimited online access. On place I take classes, I have 60 days online access and then a CD is received, which is included in the price, for further access to the class off line.
Noticed they do have some free classes, maybe take one and see how you like it.
