Query: Great if you are TTC

This product is great if you are having to test many times. The cost of the tests that you buy in a drugstore are way too expensive and these did the trick. I did buy a regular test to confirm the positive results that I got with these tests, but I really didn't need to. I highly recommend these tests to someone who is TTC and wants to test alot.
