BookFactory Lab Notebook / Laboratory Notebook - Professional Grade - 168 Pages, 8" x 10" (Ruled Format) Compare to Boorum & Pease L21-150-R, Cover is Black and Burgundy Imitation Leather, Smyth Sewn Hardbound (LRU-168-SRS-A-LKMST1)

The good: The book itself is sturdy, with rugged covers and good quality paper that doesn't bleed or wick ink. The printing is fine, and exactly what you would expect/want in a general lab notebook for documenting research work.The bad: The signatures are of irregular size and don't quite line up neatly. Some quantity of glue has leaked into the gutter, sticking pages in adjacent signatures together near the crease. This, combined with the tight sewing and very stiff binding, means that the book does not lay flat as advertised without judicious application of large, heavy objects. You can also look forward to spending a little time trying to tease apart some of the pages without damaging the printing.It's still usable, and for the price it's fine, but definitely not a top-quality product.Update: I was contacted by the seller who stated that they'd improved their manufacturing process to address the defects I mention above. They provided me with another notebook (at their expense) which was much improved over the first one I bought: it lies flat without assistance, the signatures (while still slightly irregular) line up properly, and there was no glue in the gutter. If the new one that they offered me does in fact reflect the new standard of quality for this item, then I'd probably give it four or five stars instead.

It's good. Not as good as the Boorum & Pease product I also own, but serviceable and well-made; only reason to deduct a star is that I know there's another product which is better. I will note that this product is *markedly* less expensive than the Boorum & Pease notebook; if price is important, buy this one.

Solid lab notebook with all the standard features you might need for GLP or industry. Solid build and cover as well.

Best little notebook I've ever ordered. It is so fancy and there aren't any gridlines and the table of contents is very nice. It is a few centimeters smaller on each side than comparable notebooks but I would recommend this notebook to any scientist.

I had one shipping glitch, but Amazon customer service resolved it for me. The product quality is wonderful and a great value!
