I purchased this from a used goods store about a year ago. I think I've used it less than 10 times since then. The exterior is clean. The condition rank at the time of purchase was AB+, which is quite high, but as someone who usually uses Twin Power and Stella, I feel the precision is poor. However, I don't know if this is the original level of performance. Compared to Twin Power and Stella, it's clearly not as smooth, and I can feel the gears turning in my hand. I don't know the condition from new, so please purchase only if you understand this.
