The case is almost perfect. It is exactly what I was looking for to protect my MX Ergo when I travel for work (which is a lot). Unfortunately, I have the MX Ergo that has the additional wedge for increased angle and, unfortunately, this case will not accommodate the wedge. All-in-all, a great case, but it does not fit all MX Ergo (which I found out after the return period passed).

Good

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

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.

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!

Like many others, I was worried/hesitant that this case wouldnt be able to hold my Logitech MX Ergo Plus. I went ahead and pulled the trigger on this purchase. Now while I agree with many others that it wouldve been very nice/helpful if the case was just a tad bit deeper, so as to hold the MX Ergo AND the base plate that comes with the Plus model (or just an all-around another case, specific for the Ergo Plus), I WAS relieved when I was able to find a way to store my mouse AND base plate during travels. For me, I put the base plate in the zippered part of the inside of the case. Thats good enough for me, given the options we MX Ergo Plus holders have. That being said, until an alternative is presented that DOES fit the mouse + base plate, all in one (w/o having to disassemble it, which only takes 1 second), this is our best alternative. Id recommend this case, at this time, to anyone looking for a nice case for their Logitech MX Ergo - Plus or not.

Perfect case for my MX Ergo. It fits snugly and the exterior feels hard enough that I am not worried to carry my mouse in my backpack while I travel. The zipper feels like it is good quality and I havent had any issues with the zipper separating or snagging when opening or closing. Definitely a solid purchase. I would say if youre traveling as I do, I purchased this cable to plug into my laptop for charging. It is a short cable that tucks in perfectly to the case under the mouse for storage. https://www.amazon.com/gp/product/B0744BKDRD/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

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 love this mouse! I spend the vast majority of my work hours using a computer either reading documents or writing and editing documents. My second wired ergonomic mouse finally died, and my employer had some weird style that would require me to move the roller ball with my fingers instead of my thumb. After a decade of using my thumb, my brain refused to adapt quickly enough to the new style and it made my hand ache. This wireless mouse was the perfect replacement for my dead mouse. I bought it with my own funds rather than suffer with the wonky option. After a couple of months using it 5 to 6 days per week, Im super pleased. I do have larger than average hands for a woman with King fingers. My glove size is 9 if that helps anyone judge how the mouse might fit their hand. I think that someone with a tiny hand or short fingers might prefer another style. I did buy the carrying case, and I will be taking my mouse on work trips. Its worth the space that it will take up in my rolling computer case.
