This is the second one I have bought for my second home. I use it to organize computer printed recipes how-to articles scripts etc. I wish it punched more than a few pages but it's always been reliable and gets the job done.
The Staples Adjustable Hole Punch I purchased lists itself as having a ten sheet capacity. This is true. However when hole punching a full ten pages the middle punch tends to be unable to cleanly punch through all ten pages leaving the puncher stuck in the top two pages and the user having to manually extract the middle holes that are only perforated by the puncher. It cleanly punches through eight pages about 75% of the time. I find it works most efficiently at 100% when punching seven pages at a time or less. Despite this minor setback I still highly recommend this product. I use this constantly and for the price it is a bargain.
