Purchasing this mouse is not something I recommend doing. This mouse set me back 6900 yen. Despite the fact that this mouse comes with a one-year guarantee, the customer support center refused to provide a refund or perform warranty repairs. They reported that they were unable to find a suitable spouse. In addition to that, videos of the mouse were submitted to the customer service center. Pros: The disadvantages are compounded by the benefits, but it is still a comfortable mouse for the time being, at least up until the point where the rubber bands start to tear off. Good sensor Cons: The rubber bands can be removed easily. When you move and press on the mouse, the glue that is hidden under the rubber bands emerges, and once it does, everything is contained within the glue. The most significant disadvantage is that after using it for half a year, something occurred to my mouse. The left button clamp functioned sometimes, but not always, and it appeared as though the machine was running slowly. And for a period of two months, I was under the impression that there was something wrong with my computer. Until I switched out the mouse, that is.
