I am selling this because I purchased the higher-end model (530) at the same time. As the previous owner commented (when purchased new), it was in excellent condition. This is a 520J with sufficient performance. I think it's a great buy. I hope you will consider it. "I used a red protective case, and the number of times I used it was quite small, so I think it's in relatively good condition. I used it for about 10 hours in the three months after purchase."
