The Moleskine cover is good quality. The leather is strong but still thin and flexible. The cover is wide enough to accommodate a pocket notebook (with elastic) but is quite snug. Personally, I prefer using it for pocket sized Moleskine Cahier or Field Notes (no elastic).
I've read some reviews complaining about size, color, and scratches. I found the comments both strange and hilarious. Leather is a natural product so things like color and texture vary from hide to hide and does not mean the construction is poor. I've seen someone complain that the cover was too small for a notebook it wasn't designed for (honestly read the dimensions and get a ruler). Finally, if scratches offend you, don't buy pull-up leather. Ask questions if you're not sure!
That being said, the cover is solid and the craftsmanship is nice quality. It's not as thick, stiff or heavy as some brands, but I personally like less weight and more flexibility. A+, I'd buy again from Hide and Drink with no reservations.
