Japanese quick connector is not compatible with US NPT 1/4” IM fittings and is way over tightened so it was hard to replace. Handle and trigger feel loose.Feels like a cheap dropshipped product with high margin.EDIT: after putting on a regular 1/4” quick connect adapter this has become the most versatile pneumatic tool in my detailing kit and stays on the compressor hose 90% of the time. I was pleasantly surprised by how wrong I was and how excellent this turned out to be. I only wish the hanging hook at the top was a little larger to accommodate more surfaces.
