Purchased as my older on was jamming. Machine is slick well made and works well. It has compartments for the "off cuts" and for the binding Combes - the latter of which is not much use really as it only holds a few.
The only thing is Be careful when using for the 1st time... This punches the holes in the papers while you place them in VERTICALLY, not flat like the other machine and you Must place the papers to the far left in the slot otherwise you get a mis aligned punched page. (a4). practice with a few pages first.
Also you have to really check that the pages are all down and flat before you punch them... practise makes perfect and just take your time to align and get the paperwork dead straight and flush and you will be ok.
Only downside is that the opening Flay which supports the pages keeps coming open when you move the device it would be a good idea to have a catch on it to prevent this. Otherwise a nice clean piece of kit that works well.
