Good things first Wide range of sizes in a nice box. Overall pretty well done. For the price I paid this was a great purchase. Now for the cons: As a former QA in a metal fabrication factory, I can say this is not the highest quality product. It's not much work to touch them up with a file to remove many burrs on the cut edges. See two photos that show burrs, possibly because the cutting edge was sharpened too aggressively. Other photos show light areas where I put the edge of the saw down. It felt like the beat was reversed to me, like a bunch of beats in a container were moving between stations during production and not separating them properly. This deformed the tip of the saw edge and no longer ended in a sharp point. Again, removing burrs and dull edges only takes a few minutes since all defects are microscopic. Once this is done the bit cuts really well.
