I love the classical homeschool curriculum and Memoria Press is a very good choice in my opinion. Their quality of materials is excellent and their customer service is outstanding.
I do believe that if I were to do first grade all over again I would make a slightly different choice and not order the complete box set. The box set for first grade came with many workbooks that I did not end up using.
However, I did love everything that we did use such as Rod and Staff Math, First Start Reading, Classical Phonics, Copybook II, and New American Cursive.
I hope this Classical Homeschool curriculum review of Memoria Press is helpful and I wish you luck in your homeschool journey!
