If you want your precious investment protected then get this one.. Fits perfectly for my Logitech MX Master 3 Master 3S Advanced Wireless Mouse. I know there are reviews that says its still wiggly inside and that made me think twice buying this, but went ahead and purchased it since my trip is coming up and I dont regret it at all. There is some room inside but not too much that it will damage or click a button. I also automatically turn off the mouse when I store it. The case is very well built.

When a person pays a lot of money for a computer mouse, you want something to protect it. This is the second one I have purchased (for a second mouse) and highly recommend it to anyone.

Great protective case for this mouse. Mouse also fit great.

La verdad, para este mouse…. es casi que obligatorio !!! Éste desde luego, no lo llevo de cualquier manera… es ideal, fácil de colocar y guardar, ajusta como un guante y lo protege de todo… De verdad, muy conveniente !!!

Good quality zipper. Fits perfect. Holding up great for a month or two now getting thrown in the bag with everything else.

Épouse parfaitement la forme de la souris.

La sourie est pratique par son côté ergonomique. Le pouce est posé dessus et se déplace avec. Pour le reste je n’ai pas testé les nombreuses fonctionnalités. Je l’utilise en DAO, traitement d’images et bureautique. Elle est conforme à l’attendu. La livraison a été rapide.

awesome

As others have said, this is NOT designed for the MX Master 3. It is lying when it says that. This may fit other MX mice, but it is not for the MX Master 3

Cushioning seems adequate for avoiding scuffs but rather thin for anything more than that. Opens to one side, rather than the front, which seems like a small thing but means it isnt ambidextrous. One zipper pull also means you have less control over which side to open from. I returned and have reverted to competitor products which have the features this lacks.
