Product is excellent. From the trained eye of an experienced DM, there's almost too many spells but that's never a bad thing as many of these can be awarded to the party as scrolls, turned into potions or alchemists tinctures, or other magical items.
I do wish every spell had the school listed after it. It's not traditionally important, but for characters like the Arcane Trickster, or for Wizard specialties, it would help draw the eye to what's wanted. That's not a sour enough issue that I'd remove a star, I rate what IS in the book and not what isn't in there.
From a formatting standpoint, I kind of wish there wasn't so much blank space between the school and the spell parameters, but that's aesthetics and not balance or anything. And that's all I can criticize the product on which should tell you this is a product that is well crafted, edited, laid out, and in general is worth your money.
