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

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.

Good case, it does its job and protects the mouse perfectly. I’ve been using it for at least one year, and the only issue I can mention is that the inside fabric gets dirty easily. It fits perfectly with the Logitech MX Master 3S and is sturdy enough to keep the mouse safe.

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.

Sturdy case and zips well. This is my second case as I have had my MX3 case for four years and its still looks good and protects my mouse. This one fits my new MX4. There is a place for the dongle. I use tape to hold the dongle in place. My wish list for the case would be: 1. Something to hold the dongle in place. (Velcro?) 2. a place for the charging cord. It's really hard to cram the charging cord in and zip it. Even a 1/4 larger would allow for the charging cord. I can get it in by stuffing the cord over the thumb rest.

I bought this case due to the reviews that were positive and the case was costumed to the mouse model i had bought. The cushioned case definitely protects the mouse and there is a little spot for the USB wireless link up. The only downside of the case is that there is nowhere to put the USB-C mouse charging cable…..it would have been nice to have a pocket or elastic strap inside to secure. Perhaps another zip case on the underside.

perfit fit and great protection . Was pleased that it included a ring hook to attach it to the outside of my tach carry bag .

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.

Well made and a good fit
