Here are the facts that I know:
A couple of weeks ago I saw posters hung in Kiryat Sefer announcing that this book is full of misunderstandings and invented pshatim. The posters bore the signature of my Rebbe, R. Aharon Feldman, Rosh Yeshivas Ner Yisrael שליט”א.
Whether the posters are truth or someone’s fraud I have no idea. I have not called R. Aharon to verify because I don’t use books like this one anyway, since Mikraos Gedolos is better.
