Tested Versus: Keys Duplication fiercer insight comparison We recently evaluated the 180W Keys Cutting Machine Duplicator, a double-head, horizontal multifunctional duplicator designed for house and car keys. Our setup was straightforward: we fed it several key types and observed its precision. The machine delivered impressive results, duplicating most keys within seconds with remarkable accuracy. Its dual-head design allowed for efficient handling, and the horizontal orientation made adjustments convenient. However, we noted that certain high-security keys required manual calibration for optimal fit. While the device excels in speed and versatility, its compatibility with all key types remains a slight limitation. Overall, it’s a robust tool for enthusiasts and professionals, though prospective buyers should consider its specific use cases.
