This is the worst stapler I've ever encountered. It's way too light for its size and jams nearly every time. We had ordered several of these to be "economical" - what a mistake. Each one performed in the same hideous fashion. Now they're all in the trash. Don't make the same mistake we made.
We needed a good stapler at church because the two old ones weren't worth the metal/plastic they were made from. This one is great. It's lightweight and easy to use. Hasn't "misfired" once. I love it!
