This is a sturdy product which will give many years of reliable use. There is a movable paper guide depending on which size of paper in use. It will punch multiple sheets. The holes are cleanly cut, not like some cheaper versions which leave half the paper still in the hole. It can be locked shut. I use it at home but it's strong enough to be used in a commercial environment I'm sure. It was well packed and I would recommend it to anyone looking for a good quality double-hole paper punch.
