The Discovery Education Techbook provides a good overview of information about the topics in Utah State Standards for U.S. History I and II, many good extension activities, many professional development resources, some engaging classroom activities, a solid reference encyclopedia, Spanish translations of assessments, and a good number of written test prompts. The text generally appears to lack depth, however, and the resource offers only limited assessment options. In addition, the software can be a bit unfriendly to navigate. These observations make this resource a solid supplemental classroom resource, but probably insubstantial for primary use.
