Apart from super quick shipment and amazing quality, this is the second time I am ordering and the seller just always makes me laugh. The shipping label says to great xx from horrible Rey del sol 😂.

These books are awesome. More than math. My daughter and I do them together for hours.Genius.

Extremely entertaining…my kids read the guide books as comics during breakfast. It’s crazy hard at times, but it’s thrilling and engaging.

Good

I am a math person and working with my children at home. These books are amazing
