co2CREA Hard Travel Case for Logitech M570 Wireless Trackball Computer Wireless Mouse

Really nice hard shell. I feel like my mouse is very protected.

Bought this to use when transporting my Nulea M501 trackball mouse. The fit is perfect. Nice buy.

first couple of times you put the Logitech M575 in the case and zip it shut it will be a little tight but the fabric stretches a little and the Ergo mouse will fit just fine. Zipper seems to be well made - has no frays and has no broken seams. I am glad I purchased this because it will protect the mouse from a hard environment.

This case is better than I had expected. It looks like soft nylon in some of the photos although it is listed as a "hard travel case", however I believe that is somewhat of an exaggeration. I believe calling this a firm case would be more accurate as the case will depress under a modest amount of pressure. However, I believe that it should provide adequate protection for the mouse under most conditions. Keep in mind that this is NOT a Generic Case; it is made for a specific mouse, and the MOUSE is NOT INCLUDED. I am pleased with the quality of this case and I believe it is a good value at $8.00. Despite what I feel is an error in the description, I am giving this case five stars.

Let's be clear, despite the product description, this case was not made for the Logitech M575S, and it does not fit. You can force it to fit, and it's close enough to get it closed, but the case wasn't designed for it. The depression in the lid for the trackball isn't even in the right spot. It was clearly made for an earlier model, and still close enough that they can market it for the M575S. It will do the job of protecting the trackball during transit. But it doesn't fit like a fine glove, it fits like a boot you found while walking barefoot, better than nothing.
