This is a product whose value (especially price first) is valid. After reading the reviews, I was not necessarily expecting something effective. Yet the results are clearly legible on the strip. Certainly, there is a minimum of 30 minutes + 10 minutes resting display of results to be respected, but the game is worth the candle. The record is very clear. And the result seems reliable because J-2, the test became positive! And obviously (good trait darker than the test line). Purchase really done without regret, I have the same price for 2 bags do not have to pay postage, and can use them without counting!
