Birch Boys, Inc. review for GS Demographics

I was very curious to see what our 24,000 customers who were analyzed proved to be in terms of gender, ethnicity, and age (mostly age data is what i was looking for). I have a pretty firm grasp on who our customers are and the results seem to mirror my understanding to a very strong degree, with some slight unexpected nuance, and therefore I cannot say with certainty but it is my opinion that the other 1 star review who said these results are bogus is simply not the case for our customers and my experience with this app. Give this app a chance, it seems very useful
