Perhaps better battery life will be worth the upgrade.

This one must be lithium because I've only had two charge it once a month after being very careful to turn off the device when not using it at night as this saves the battery life and outperforms any other mouse I have ever purchased in 25 years of computing

What can I say; the unit works very well and the battery life is outstanding.

And the battery life is incredible - I have had this for a couple of months and have only recharged it twice.

The battery life is crazy

Battery life is outstanding!I purchased this mouse in Grey to match with my MacBook Pro 2017 in Space Grey

They made it way better, more responsive on literally any surface, more customizable, more than twice the originals battery life, maybe three times

The battery life is awesome

Battery life is great

The battery life is much improved lasting about 2.5 weeks between charges with daily 8 hr use.

Also, the battery life was ok (not great).

The battery life is lengthy which is a great boon to swaps between platforms, and in constant use of the product on a 10-14 hour day

Plus its even longer battery life is just amazing over the previous model.

Third, since the MX Master has a non user-replaceable rechargeable battery, the relatively short battery life is a nuisance

Battery life is good

I’ll just start off by saying the battery life alone is astounding

Battery life of this mouse is really amazing

I've never had any battery life issues with my other Logitech mice, so I am not sure how useful the "up to" 70-day battery life is.

Battery life is pretty good, got 6 weeks out of a charge with medium-heavy use.

The battery life on this mouse is great

Battery life is good

The battery life on the mouse is very good too.

The battery life is awesome.

Battery life is fantastic.

The battery life also feels much better on this iteration

Battery life is phenomenal and it's well made

Battery life is incredible

Good buttons and battery life, accuracy, customizability

Really like the mouse Only issue I have with it is the battery life

The MX Master 2S has higher dpi (4000 vs 1600), longer battery life (70 days vs 40 days), and the most important thing to me, it has the Flow software which provides seamless control of up to 3 computers with using the one mouse

Battery life is great so far

pockets.- Battery life is amazing

Excellent mouse, battery life is great, the feel is awesome

Finally, battery life has so far been excellent - I haven't had the mouse long enough to wear it out despite several days of use

The battery life seems decent, but not great

The battery-life is fantastic and in the couple of

The battery life seems excellent, and the build quality is the same as the MX Master--it feels good in the hand.

Only one point to criticize (same as it's little brother) is that there are no warnings if the battery is running low

Perfect! A+++

a while later it doesn't work as it's supposed to and now it's nothing more than a ineffective paperweight.

Work exactly as I expected or even better!!!

Since it's a laser mouse I am able to use it on a glass table top as well as on blankets and wooden tables.
