Query: Does not meet professional standards

This video does not meet professional standards for the industry due to the fact that it shows sign language concepts that are less than basic. For most of my students they have passed this level in the firs quarter of class. These examples are in everyday speech and can easily be practiced with a real Deaf member in your city. I believe that this may be just a quick scheme using our language as a means to profit instead of providing real language concepts that can be reviewed and used as a dictionary or reference guide. Other tapes of much higher quality give at least 60 minutes and provide topics and concepts that will encourage the viewer to be motivated to use. Also I do not recognize any of these individuals as persons from any deaf community I have been involved with. This appears as a "vanity tape" instead of a real educational video.
