If I'm using a red keyboard on my tablet and I have to use the mouse for a long time, my fingers hurt. So, it was Mauson, and I bought it with a dubious dissatisfaction because it only came out with support for Windows OS in the public home. First of all, the BT connection is good, and the feeling is better than I thought (?). It spreads flat, so I don't think there is a mouse like this in storage. I also like the design.
