Booklist, in the May 1, 2009 issue, writes the following about Suzanne Bloom's A Mighty Fine Time Machine:

"Children who have ever created anything out of a box will identify with the trio’s ingenuity. The colored pencil-and-gouache illustrations add warmth and humor to the story. Bloom’s whimsical word choice will further draw children into the story and have them rooting for the friends’ success."
