Nice case but listing said it came with extras. There were no extras but its a good case for my trackball.

when traveling. Mouse fits nicely inside and keeps it safe when having to travel on business.

Good

This mouse case works great for school. It protects my mouse on the outside of my backpack.

Ive been using trackballs for a very long time. I have a tech backpack that I use for work. While the laptop compartment has good padding to keep it separate from the larger compartment where I carry my tools, the smaller compartment where I was storing my trackball didnt seem to be as protected either from the tools inside of it or anything outside of the backpack that it might bump into or fall against in transit from one customer site to another. I didnt even know these types of cases existed until they showed up in my Amazon Recommendation after Id bought some new/upgrade balls for my existing trackballs. And, as soon as I saw that the cases existed, i knew I had to get one because it would address the growing concern that I had that the trackball might get broken at some point. The hard case gives it the protection it needs. And, because of its clamshell design, you can also just open the top and leave the trackball in the case while you use it.

I travel quite a bit with my beloved trackball. I really feel like I have responsibility to go out into the world and let them know what they dont know, the joys of trackballs. Im often met with quizzical looks and bewilderment, people struggling to determine what manner of device I possess. Upon knowing, they find it incomprehensible that such a device could be functional. its a heavy burden, to be sure, educating these poor lost souls. Nevertheless, I take it on willingly. But if Im going to travel with it, how am I to protect it from the horrifying buffet of hazards along the way? I often ride a motorcycle, it gets banged or crushed in the luggage. Heavens me, what to do? I have to get this device to the public so they, too, can buy one and live fuller lives. A soft case isnt going to stop it from being crushed! What you say?!? You have a hard case with a soft interior?!? How is that even possible! Anyway, long story short, Im saving lives out there, and this hard travel case for my Logitech M570 supports me in that noble goal of trackball evangelizing. Please, anyone reading this with a mouse in your hand. Stop it! Theres so much more for you in this world!

Everything fits in case. Case is solid.

The MX575 fits like a glove (almost) and I definitely feel that my house was protected while using this hard case. I had no trouble closing and opening the case using the zippers aside from an occasional snag with the inner fabric lining. My only issue is that I wish the carrying loop was small or non-existent as it seems to just get in the way with how long it is. I, personally, do not have a use case for this large carrying loop as the case just ends up being loaded into the main compartment of my bag. But, all in all, its a good case and I recommend it to anyone looking to protect their mX575 but are willing to deal with a long carry loop.

Perfect security companion for the Logitech Ergo MX mouse. No issues at all, fit is perfect, soft interior protects well. It would be nice to have a dedicated place to store the USB dongle, but that in no way detracts from quality or compatibility. Maybe just an idea for a future version.

This fits the Logitech MX Ergo Wireless Trackball Mouse Adjustable Ergonomic Design perfect. I also lay the charging cable on the bottom and place the mouse on top and I’m still able to zip it close!
