Depends on the definition of "useless" :) They used to be better until FDA cracked down and prohibited them from providing a detailed analysis of the DNA results where they would do a very decent breakdown of what kind of decease you might be predisposed to based on the results etc. From what I understand they still do this in Canada though, also there are online services that can take your results and provide some sort of an extended analysis, never dealt with them though.
