Everything is good for the most part

The right mouse click button is weak and this is the second one I have purchased. Everything will work fine for a few months and then you need to start pressing down firmly to make it register. It is overall not something to purchase especially if you're using it for Autocad or Fusion 360, it tends to get really frustrating.

I feel you may want to get extended warranty on this product or look for something else

- great battery life - I'm on the same batteries since I got it at then end of Dec 2015 and have almost never turned it off - side scrolling wheel - shift between clicky scroll wheel to smooth - comfortable

- no frills

I'm surprised by the bad reviews here because this is one of the best mid-priced mouse I've ever used.

None

Terrible mouse. It was okay at the beginning, but after a few months, it seemed to have a mind of its own. The scroll was off balance and did not work properly. Also, the left click button had issues where I had to click several times for an action to occur

There are other mice out there which are better for the same price. My opinion is to stay away from this particular model.

Performance, reliability, features, comfort, battery life

Side scroll isn't good

This is by far the best mouse I've ever used. I've used one at work and home for 5 years, just replaced the one at home and replacing the one at work today. Both started showing signs of age a few months ago, but I'm an avid gamer and video editor, so they get heavy use. I feel like these people giving it negative reviews for bad scrolling are talking about when the mouse wheel is unlocked. It has a lock button for a reason...you only unlock the smooth scroll when you need it.

After about six months starts to skip and causes programs to hang. All in all, Crap!!!

battery life

the screen scrolls even without having your finger on the scroll wheel. The Wheel is unbalanced and that's why it keeps scrolling....

Find yourself another Mouse

-Extreme battery life -Comfort -Hyperwheel

-Surface finish wears a bit too easy

This is by far the best mobile mouse I've owned. The First one I had lasted 4 yrs 3 of which were on the original batteries, being used everyday till the left click gave out mid 4th year. Bought a second one and still just as happy.

comfort

this mouse and several other performance mice from logitech are garbage. The wheel is screwed. the screen scrolls even without having your finger on the scroll wheel.
