I got this is as a gift from a friend and I absolutely love it!
Love the size and design. The paper's pretty thick, but definitely note entirely bleed-through proof, and the binding isn't as neat as it should be. The quality is overall just a tad lower than I'd expect for an $18 notebook.
The lie flat binding is amazing to write in! While the dots are a little bigger than I like, the whole feel of the notebook is super fun and pretty!
I use it as a workout diary and I love it.
