Teitz – “Rabbi Chaim Jachter has already established, through his first book, his ability to present difficult halachic questions, to cover them from all perspectives, to explain and clarify the views of the great poskim [halachic decisors] — both from previous generations and from today, and to explain them in a clear and understandable format, in English and in an order that makes it easy for the reader to understand the subject in depth.” (From his review of Gray Matter II)
  • Rav Shlomo Wahrman – “Rabbi Chaim Jachter answers not only “what” and “when” but also “how” and “why”. This work is truly full and overflowing. All his words are organized beautifully in a clear and flowing style.” (From his review of Gray Matter II)
