These are very accurate test kits but several steps are required to get a reading. My only complaint is that the plastic syringe markers rub off as others have said so you have to be very careful not to touch the numbers. So if you're willing to take the time to prepare your tests and have the spare syringes you have, I highly recommend this test kit.
