We purchased the Pulsarв„ў E 300 Electric Comb Binding Machine w/Starter Kit, to bind our handbooks and small classroom projects to give them a more professional look. It is very easy to use once you learn how to properly insert the combs and make sure the papers are placed correctly for punching. I usually don't punch more than 10-15 sheets at once just to make sure they align properly. Once you position the papers to punch, all you have to do is push the button to punch them, no manual punching needed. One of the reasons I chose to go with this binding machine. This machine has worked well for us.
