 It's a lot of meetings where we're had in a week, two weeks time so that we can ensure that the products that we were bringing in were viable, were safe, were reliable. We had been told by the manufacturer of the test and the literature that it was 93 or 97% effective, which is great. Doing our controls, we didn't like the results that we were getting because they weren't anywhere near. And so we couldn't use them and we decided not to use them because they weren't a good product.
