I have done two tests for the reviews, once with water and once with urine. I was there very insecure that here but so has the one or other written that his water is pregnant, so I wanted to have clarity. The test with water was so that, in fact, an evaporation line can be seen. This is easily visible pink. The test in the urine was so that the positive result significantly from the "water test" took off. For women who wait hibbelig it to get pregnant, like the trial to be nothing. For the price but it's always in the budget to make the water test as a comparison and take inspiration from them. If that's too much effort is, who can then pick up right tests, but all in one, I think that you can buy here for the price-performance ratio a good test!
