Some HF tools are good others aren't so good. Their brad nailer uses a heavy cast nose cover on the gun and I've used it for 3-4 years regularly. However, the stapler/nailer that you bought may have just a stamped steel nose cover. On the one I bought, the first time a staple hit a hidden nail it jamed up and bent the nose cover. As usual, HF gave a refund on the gun. I then bought a brand name stapler with a cast iron nose cover.
