The first thing I noticed about the AFM Disabler was its solid build quality. The design feels robust and well-crafted, and it fits snugly into the port without any wobble. This isn’t just a flimsy gadget—it’s a premium product that delivers on its promises. I feel confident relying on it for every drive.
