Query: Poor quality

This came very highly regarded by professional carpenters. Unfortunately I think they had used the US made version. That's the only explannation I can figure for my experience verses theirs.It was awkward to use. I thought it would save my back, but it still requires bending over while positioning the jaws over the nail head. But the bottom line is that it started to break after just eight nails!The good news is that the Amazon Marketplace vendor refunded my money quickly without a hassle. I applaud them for good customer service.
