Hello - We're sorry to hear that you're having difficulties with one of our staplers. We will need to know which stapler you purchased in order to assist you. Feel free to reach out to us for help at customercare@arrowfastener.com or 800-776-2228. We also suggest making sure the staples you're using aren't tool long for your application, which could cause the stapler to jam.
