Hello, there. We're sorry you were disappointed with Arrow's T50ACD Compact Electric Staple Gun. There are a few things that could be affecting the performance of the staple gun. First, this tool does have a contact safety, so it's helpful to be aware of the size and placement of the contact safety, and then place the tool accordingly. Typically this is more a matter of positioning than force. Second, the size of staple used for your project can affect the penetration of a staple. For example, if you're stapling a thin fabric into a hard wood like oak, plywood or MDF, we recommend a 5/16-inch staple. But if you're stapling thick material and batting into a soft wood like pine or Douglas fir, a 1/2-inch staple is more appropriate. In addition to picking the best size staple for your materials, one thing that can increase staple penetration when working with a hard wood is placing a hand on the top of the cap of the tool when firing. However, we know this may not fully address what you encountered. Please let us know if you have any further questions or experience any other issues. You can reach our team on social media, by email at customercare@arrowfastener.com, or by calling 800-776-2228. Thank you for your feedback!
