I was pleasantly surprised by the quality of this notebook. I was looking for smaller manuscript pages that I could easily carry around with me, just in case inspiration struck, and this notebook fit the bill perfectly!
The book itself isn't flimsy. While it won't last forever, the cover is tough enough to withstand being stuffed into your bag many times over, or at least until you've managed to fill it all up!
The paper quality is very nice too. I've come across manuscript paper that's almost as thin as bible pages, but this paper holds up well. Most importantly, it doesn't show what you've written through the page, so the entire notebook is usable.
Overall, this is a very high quality notebook for the price. I only bought one to test the quality and I regret not ordering a few more!
