Thank you for viewing. When my child was between 0 and 1 year old, I needed a silent mouse to avoid waking them up, and I used it for about a year. I no longer need it, so I would like to offer it for sale. The silent performance is very good, and I think it's suitable for those who just want basic performance. However, it is a compact size, so please be aware that it may be difficult to use for those with large hands.
