Clear Blue Easy Fertility Sticks...????

Ok guys....so I heard awesome reviews about the Clearblue Easy Digital Fertility sticks... I thought they were awesome! A :-) is a peak day and then open circle is not. However, I tested and got a :-) and then just out of curiosity but the thought tested again and got an open circle. Has anybody else experienced this inconsistency in test results? Thank you!
