Hermitshell Hard Travel Case for Logitech M570 Wireless Trackball (PU)

Snug fit, yes, but still fits and works great. I like this case, felt lined inside and sturdy outside. Yes, there is not spot to place the Unify receiver, then again, nor does Logitech provide an inside compartment as well. I place my receiver inside near the thumb spot and it stays fine. I usually leave the case attached outside on my backpack and it has withstood TSA screening, inside overhead bins, and constant moving without any problems.

It works! It is easy to handle, grip and (un)zip. I have a trackball with a cord and it fit inside just fine.

Fits perfectly, metal clasp works fine for my purposes (which are not heavy-duty).

Excellent case, it fit like a glove and it even comes with a clip so i can attach it to my backpack. The inside is lined with a very soft material.

I love this case! It protects my trackball from dirt, debris, and damage while bouncing around in my bag. I love that it is a hard shell that is formed to fit my trackball.

Really solid case, looks great, inside is nice and fluffy as to not scratch up the device. :)

The best mouse I have ever had. I now have three of them for different machines.

excellent product, still works

I bought 3 cases for my 3 Logitech trackballs from 3 different vendors so I could tell them apart visually. I have them each married to a different laptop and I thought this would reduce the times I grab the wrong one. A side effect of this is that I did an unintentional head to head comparison. The HermitShell blows the others away. It is the most compact with no wasted space. Its fit and finish is far superior. The zipper operates smoothly without snagging on the edge of the case as the others do.

Works great !! Love it works great with lightroom..
