This Periodic Table was a Christmas present for my 10 year old grandson. When he opened it, the entire family was in awe for its information, easily read and excellent quality. He was overjoyed - "Mimi, just what I wanted"! He and his father immediately mounted it on his bedroom wall (all other unwrapped gifts still sitting on the living floor). He reads it everyday and is much impressed with the factual information presented in a professional poster. His 5th grade class will be studying this subject this semester. Needless to say, we all are impressed by its quality and reasonable price.
