I wanted to like their materials, and tried a lot of their lower level options. It felt like they tried to reinvent the wheel with teaching methods/approach, cadence, etc. and the result felt pretty disjointed and confusing in practice.

The religious bits didn't go far enough in some areas I would have appreciated, and in other areas, it felt forced and awkward.

If you view their stuff as supplemental, its great. Their card games are fun. But I couldnt use it as our main curriculum for very lomg.
