Anyone else noticed these days FRER test have the worst indent lines? I tested 4 times using these last week - 2 different batch numbers on the box - and had a noticeable line on every one. There wasn't any pink to it, but the line was obvious enough to give some false hope. Fortunately I had done some googling and found that these indent lines are popping up very frequently.
I always thought FRERs were totally reliable, and a line is a line... apparently not!
