After purchasing new, a stainless steel washer has been added to the stem of the switch inside to shorten the stroke. Because the inside is a stainless steel washer, there is no wear and tear, and it has a crisp, satisfying sound. Usage time is about 4 hours. Operation has been confirmed on Street Fighter 6 for PC. Accessories include the standard shaft, instruction manual, USB cable, and everything shown in the photos. Anti-slip pads are already attached. There are no pets or smokers in the house.
