Rated after using it for nearly half a month, it’s really good, improving my work efficiency a lot. The workmanship is neat, edges are polished smooth with no burrs to scratch hands. Logistics speed is normal, the packaging is simple but sturdy enough to protect the goods well. It’s really worth buying at this price.\n
