Query: Worse Staple/Nail Gun on the Market

After using this staple/nail gun until the staples ran out, I attempted to reload with more staples. I could not open the chamber in a normal manner. I had discarded the instruction manual on the first day and I had no idea how to reload. There were no instructions, arrows, words, or even clues printed on this gun like the Arrow Staple guns I had purchased in the past. After several attempts to open it, I went to the manufacture's website and downloaded the user manual (16 pages). I followed their instructions very close and again tried several times to open the chamber. Still no luck. After 10 minutes trying to reload it, the staple gun broke.Potential customers BE AWARE, this gun has the worse design for loading staples. The manufacture failed to print arrows, instructions or even give clues on the gun as to "how to reload". The user manual was useless with hard to follow instructions. Two thumbs down on this device.Disappointed customerSam Boulton
