On the whole this machine is value for money. You do need to use a combination of common sense with a solution focussed attitude to get the best results from this machine.. It's not German made, and therefore not perfect, and very cheap for what you can get from it.
I've used it to crease and perforate thick A4 Card 350gsm after spending a little time fine tuning the rather flimsy adjustments . Once done, near perfect results.Allow for some waste material during the setup process. .
