So far I had no problems using. The ring mechanism operates reliably and accurately.
The black cover survives jostling no signs of wear.
It is provided no way to mark the binders from the outside to distinctive purposes.
I einhefte the notes in punched pockets, the four-ring technique has proven.
If I had to each punch by hand via two-punch, I would probably for two-ring version
access and the increased mechanical game when turning accept.
