Pros Very good product. The opening and closing operation is very good an won't pop open by mistake, dumping your charts.
Cons No Cons found with this product.
General Comments The leather binders are a good step up from the Sporty Vinyl binders.
I have both types since I live in an area requiring multiple binders. I use the bonded leather for my primary area of flying, and have the blue vinyl binders for the surrounding NOS chart coverage area that I only go to on occasion.
The bonded leather is very good quality and I am very happy with it's appearance and operation.
A very good product for a reasonable price!
