I am so pleased with this binder, and it has come in so useful for so many things, including creating colouring books for my family.I know it is a considered purchase and I really did do a lot of hunting about for the best price, and this met all of my requirements. A lot of the cheaper ones do not bind as many pages and so paid the small extra so it had more use.Definitely a great buy if you need any type of documents binding, and although the combs are more expensive than the plastic ones, they are far superior in my opinion.It can take a bit of practice to get the coils to bind correctly but this is a small price to pay considering how useful it is
