What is your opinion of this product?
Disappointed - The lines are not marked right and left - you get two identical sets that are not attached to each other, so you have to guess. The top lines are about 1.25" longer than the bottom lines. Luckily the two top lines are equal and the two bottom lines are equal, but they are not equal top to bottom. I expected more for $78. If I am wrong interpreting the description - please let me know. Everything else I have purchased is top notch.
