I have used the test on two of mine. It has been extremely helpful and pretty much right on target. I've had no issues with customer service. My thought is that vets aren't going to like a test that takes a huge amount of money out of their pockets. It's pretty similar to those vets that are against raw but push hills and royal canine. I have recommended this test to a couple people and they had no issues either.
