Hermitshell Hard Travel Case for Logitech MX Master 4 / MX Master 3 /MX Master 3S Advanced Wireless Mouse-2.0 Upgrade Version No Shake (Black)

This case does exactly what it’s supposed to do, and it does it very well. The fit is perfect for the Logitech MX Master series. The mouse sits securely inside with no movement or shaking at all, which was my biggest concern when traveling. Once zipped up, everything feels tight and well protected. The hard shell feels solid and durable, offering real protection against drops, pressure, or items shifting around in a bag. The inside is nicely padded and shaped to hold the mouse in place without pressing on the buttons or scroll wheel. I also like that it’s compact without being too tight. It doesn’t add unnecessary bulk, and it’s easy to throw into a backpack or carry-on for work or travel. The zipper feels smooth and sturdy as well. If you own an MX Master mouse and want a reliable case to protect it, this is a great option. Simple, well designed, and effective. Easy 5 stars.

I'm excited to write this review because I purchased/compared 4 cases for my MX Master 3S and found this case to be perfect! The mouse fit perfectly snug in this case...no rattling around inside. The USB receiver actually stays secured in its storage spot without relying on the mouse to keep it in place. The interior bottom is exactly molded to this mouse and is well padded. Both top and bottom shells are very hard/strong, and they actually seal against each other when you zip the case closed. The result of this design is a unified shell that protects very well against compression when stowed in a full backpack or suite case. Two of the 3 other cases I tried were $20 and the 3rd was $10, and those were all 3 or 4 star reviews from me. This case would have been a 5 star even at $20+, but this one comes in at $15, so it's a great value, too.

I carry my MX Master in my backpack to use with my laptop (I hate the touch pads). This case does an excellent job at protecting my mouse as it jostles around with the power supply and various other things I put in there with it, and it doesn't show any wear after almost a full year of use. My laptop has blue tooth already, but I do carry the dongle in the case should I ever need it for some reason. The dongle fits well in the place for it, but it isn't a snug fit and will fall out easily when you open the case. But there is a solution. I placed the hook portion of a Velcro strip over it in the case and that has kept it securely in place for the last several months I've using it.

Worth it 10x over. Super slim and wraps around the device. Worth every cent. Use this every day because I need it for on the go. Very solid quality and feel premium.

I like this! The hard case is definitely better to shockproof these expensive optical mice saving money in the long run. That it also has a little depression for a valuable Logitech Bolt USB receiver is such a nice touch, too. Very convenient. No digging around in the laptop bag... I use a protective rubber guard for my USB Bolt/receiver, and, though it fits well enough without it, it fits a little more snuggly now such that I won't worry quite as much about it getting loose or possibly falling out if the case gets a jarred. But the zippers are high quality too. Anything going in there is safe and sound. It's good quality construction that's better than any cushioned nylon bag to protect your devices.

It is of good quality. I travel with my wireless mouse back and forth in a back. It prevent unnecessary pressing of the keys. It works.

I love this case, it’s durable, and easy to transport. It is well made. It also comes with a clip, and it keeps my expensive mouse safe. Super functional and worth every dollar.

This is a great case for the MX Master 3/3S. Been using it for over a month now and I really like it. I don't use the USB dongle, but I just found mine in the MX Master box and thought it might be good to keep incase I need it. I thought I would see if there was somewhere to put it in this case with the mouse and sure enough, there is! There is an embeded spot right below where the mouse sits for the dongle. I appreciate that detail, and for that reason, and the fact that I've liked this cased for over a month now, I decided to give it a good review. Lastly, my favorite thing is the design of the zippers. Instead of having bare metal zippers in my bag scuffing my stuff up, they have a soft cover over them whith a nice little deisgn.

As expected

Tengo el Master MX 3S y este estuche le encaja perfectamente, los materiales se ven de buena calidad y protege al mouse cuando lo llevo en la mochila. Tiene un hueco para guardar el dongle que trae pero yo no lo uso para que no se pierda porque no se queda fijo, habría que ponerle un trozo de cinta adhesiva para asegurarlo. Por lo demás es excelente, sin duda lo recomiendo.

Muito boa ela, vale a pena o investimento, só cuidado com golpes de fakes que se passem por uma importadora.

Perfetto per il mouse, robusto e ottimo rapporto qualità prezzo

It fits well with Logitech mx master 3 mouse, the reason for only 4stars is the price is too high for a protection case 🤔😝
