The Reverse Book is my favourite in the Rhodia line, and I have tried just about all of them.
In general, I prefer wirebound notebooks, and after many years of trial and error, I've come to prefer the wires on top; the Reverse book can be used with the wire on top or on the side. Most ruled products are too wide for my small writing, and that applies to Rhodia as well, but their dotpads are perfect.
I also really love the size of the Reverse book—no more buying A4 products to keep at home and A5s to take with me. I can do whatever I want with the Reverse book, because it's big enough to use on my desk and it easily fits in my bags to take with me.
I always have several Reverse books on the go at a time for different purposes, and I love the clean and simple look of Rhodia products, not to mention the most important reason I buy them: the quality of the paper!
