Logitech today announced an updated version of its MX Master series mouse, the MX Master 4, which features haptic feedback and introduces a few other changes while remaining largely faithful to the original design.

Apart from cleaner-looking frosted buttons and a more minimalist bottom, the MX Master 4 looks very similar to the S3. The feel is, however, slightly different – the new model swaps its predecessor's soft, ribbed finish for a smooth, hard-plastic body and buttons, although there is some softer material around the right-hand side and on the surface where you rest your thumb.

The new haptic feedback delivers subtle vibrations near the thumb for scrolling, navigation, and selection. Haptics also accompany gestures and shortcuts accessed via the Actions Ring feature (now with a dedicated button under the thumb), which can be set up via Logitech's Options+ software. You also get vibrations with a low battery warning or Bluetooth pairing.

Logitech has also updated the MX Master 4's connectivity. The mouse now ships with a USB-C Bolt receiver for lower-latency wireless connections and improved security, while still supporting Bluetooth for multi-device pairing. Battery life is still claimed at up to 70 days on a full charge, and fast charging via USB-C can deliver three hours of use in just one minute.

Other improvements include quieter, more precise clicks, double the connectivity strength, and an updated MagSpeed scroll wheel that promises smoother transitions between ratchet and free-spin modes.

The MX Master 4 is available to order from Logitech's website for $119.99 in Black and Graphite Charcoal color options, with a Mac version available in White Silver and Space Black. Shipping starts early October.

Definite buy for me! The biggest irritation with the last iteration was the soft plastic shell - great for a year, but anything longer and the plastic starts to break down. 5 years later, it's in bad need of replacement. I expect the hard plastic will survive for many years longer.
 
I tried the MX Master 3 for about three weeks but ended up returning it for the MX Anywhere 3S. It was just too big for my taste and I didn't find it comfortable...but I get the appeal.

At work, I use a 12 year old M510. Still works fine and is super comfortable.

I bought the 3s for Mac last year and not noticed any degradation. I have to say it's easy the best mouse I've ever owned. I do wish they could implement a scroll ball of some sort for true 360 scrolling but other than that I can't fault it.
 
Did I just get transported back to 1998? Very retro and not in a good way.
Yeah, this looks nothing like that and you’ve never used the MX series have you?

It’s the mouse that no one can live without after they use it. It’s freaking fantastic. Now the Apple magic mouse still looks exactly like it did 20 years ago, so there is that.
 
I have never loved the mouse as much as I love the MX series. I have it in black and white and looking forward to seeing if this improves stain resistance works.

I like the soft rubbery grip, but it does get kind of funky after about a year. Hoping the hard plastic doesn’t turn out to be a cost. Savings passed off as a feature. And looking forward to an improved scroll wheel.

Never been a fan of the big scroll ball, but I also hear you. The side scrolling button is great but when I’m in the website, sometimes I want to scroll left or right or on a spreadsheet and then it wants to change to a new tab. I wish they would add one button just so you could toggle between your programmed actions for the side stroller button that I don’t know what to really call it.
 
Curious to give this a shot, since abandoning my previous model with the softer finish that felt grimy from minimal use.
 
Just wish they'd make a larger version so my wrist and right side of my hand aren't dragging along the desktop.
 
One thing that isn't clear from anything on their site… Does the MX 4 get the same "silent" clicks that the 3S has?
I have a MX 3 Mac edition and love it. I've been intrigued by the 3S, but can't justify replacing mine, when it still works fine.
This one looks cool… but does it have the silent clicks or the "clicky" clicks? Will there be a MX 4S coming out eventually?
