I purchased 2 pads. I have only recently started using engineering pads again. I used them in college, but do not recall the quality of the paper from 20 years ago.These pads have all the features I expect.1) light green paper and is low glare. - Very important for me as I get older.2) Top margin is 1/2 inch. - Seems good for me.3) Right margin is about 9/16 of and inch. - Seems good for me.4) Grid area is 7" wide by 10 inches Tall. - Just like I remember5) Grid is just visible from the front even in poor light. It is faint enough so it is not distracting from the drawing and calculations. - Perfect to me.6) Erasing of HB pencil marks is easy and does not compromise the paper or the grid on the back side.There are a couple of issues, which may be big for some.The top margin line is not always right on top of the top grid line. It is right on for some and on other pages, from the same pad, it is off by as much as 1/32 above the top grid line. This is a very minor/non issue for me. I never mark right up to the margin anyway and only noticed it when I decided to make a overly precise review.The side margins seem to be pretty consistent and are always within the thickness of the lines. No more than 1/64 off on the pages I have checked.I am using them for calculation and rough diagramming of problems, so precise alignment of the margin and grid do not affect me at all. I am very happy with them and I will definitely buy them again.I thought about 4 stars, but chose 5 as it is perfect for my use and is relatively cheap. The issues I found are nit picking. I would not have even noticed the margin issues except that I decided to do an OCD like review.My exact star level would have been 4 and 31/43rd stars, which rounds to 5.
