Review on COMOWARE 20Pcs Rotary Hammer Drill: High-Quality Power Tools for Precision and Efficiency by Jorge Kumar

I received the same set of drills: https://smile.amazon.com/gp/product/B07RY8FV2G/ Excellent quality. With a Bosch hammer I drilled 16 holes with a diameter of 18 mm and a depth of 20 cm in solid concrete in about 10 minutes. These are SDS+ metric solid carbide drills. How can a reviewer complain that they received a metric drill when they ordered a metric drill? And how can they complain about the drills being dull when carbide drills are dull by definition because they chip and don't cut like wood drills?
