Hermitshell Hard Travel Case for Logitech MX Master 4 / Master 3S / Master 3 Advanced Wireless Mouse（2.0 more compact upgrade version） (grey)

I would like a better storage slot for the USB receiver but other than that, it's spot on for the MX Master 3

Bought this for my new MX Master 3 which I wanted to travel with on a dialy basis (I use the mouse with a Desktop at home, personal Laptop on the move and a business laptop both on th emove and in the office). This case is perfect for those situations, it only adds the necessary bulk to protect the mouse, no more/less.I had read that some people had fitment issues (too big and rattling around, or too small and buttons being permanently pressed) but my one seems to fit absolutely perfectly! Closing the case on the mouse, it does not appear to press any buttons and, once closed, still no buttons are heard to be pressed and shaking the mouse I can hear no movement of the mouse within the case at all.There is a slight flex to the case and if the top of the case is pressed fairly firmly you can hear mouse clicks through it, which is totally understandable but also proves my previous point that they are not pressed with it closed.Pretty much the best case you can get for the MX Master 3 at this time. Very happy with it!

I thought this product was better than what it is. Sadly the zipper is of a bad quality and opens by it self. I'm disappointed the mouse can not be secured proper in the case, eventually with a velcro strap. Several the mous has fallen out because of the bad quality of the zipper. Also there is no room for the charging cable, too. That would be nice. So I need to transport the cable in another pocket of my computer briefcase and have the mouse in the Hard Travel Case. It disappointed me, as I normally are very fond of the products from Logitech. However, here you missed something important when you also have sold a mouse with a charging cable and not made space for the cable in the hard case. The hardcase itself is very sturdy, but somehow the zipper and lack of cable space ruins the great product of a sturdy case.

This is excellent, mouse fits snuggly and is well protected in a semi solid shell case.There is an indent for the USB dongle but it does not secure it.
