Bought it in October 2016 and apparently the scroller is broken. it takes a lot of pressure to click the scroller button.
the product was comfy to use however longevity is a major issue.

final verdict : I would not recommend it to Designers or architects. who have heavy usage of scroller button.
However it should work perfectly fine with people who do a lot of mails, internet, etc.

This mouse is the best in its price range. Totally worth it.
The smooth scrolling isn't exactly anything fancy like what is shown on the website, it just smoothens out the scrolling animation instead of the page jumping downward every time it clicks. The story about the momentum and being able to scroll through fast by flicking the wheel is so not true. Maybe that's a feature only on the more expensive logitech mice like the MX performance and marathon.
The click noise is just right, not too...

I am now using this product for over a week and after using different wireless mouse over years this is the one which can be compared with the one I have of apple mouse. The color is good, quality of material is good, and its interaction is also, good with both desktop and laptop. The shape of mouse is also, very good not too small and not too big fits well under palms. A very good product to purchase.

The Logitech M280 is a wireless mouse worth buying that too in such a low cost.
Its finishing is extremely impressive and the rubber grip at the sides is awesome and looks fantastic.
It is a normal sized mouse and its buttons are smooth and light to press.
This mouse is a perfect device in its kind.
Absolutely Awesome. :) :) :) :)

Amazing product, fits good in my big hands, works precise and great, design and look is also really good, battery and it's life is long enough. The only problem is the built material, it feels so plastic and toyish for the price, my first impression on the material is not really good. Except for that it is a great product to use

Reviewing after 2 weeks of Everyday office use.

Pros -
Looks : its a traditional mouse, but still looks much much better than the normal mouse and the textures around the mouse just makes it a view to watch and touch.

Ergonomics : its amazing to touch and keep your hands over it. The way its made for your hold, makes it so comfortable.

Noise less : there's no unnecessarily click noises, which is a great plus point.

No optical light : the light sensor below the mouse doesn't emit any ...

IT'S A WOWWW. Bought it on 7th December 16 and it's been a pleasure. Till now. Haven't seen a mouse that comfortable and is red too. Logitech is a classic and a very reliable and elegant brand. I love it. My hardware for computers will be Logitech for quite some Time now.

Logitech products are unparalleled!

Pros
- Very Ergonomic
- Good Premium Finish and Feel
- Great Performance
- Fits well even on a large wrist
- Hassle Free installation and place to keep the Bluetooth receiver within the mouse.
- Rubberised sides for better grip.

Cons:
- None

A must buy if you want one that performs well for day to day use with laptops and desktops. Great for the office goers.

Pros :
1. Plug and play, no drivers needed, just plug the dongle into the system and it starts, just like that
2. Very good sensitivity, tried using it on my palms!! and to my surprise it worked flawlessly even there as if I was scrolling on a mousepad
3. Ergonomic design, the rubber padding makes it very comfortable to hold
4. Contains an inbuilt slot for holding the dongle, so maximizes portability greatly at the same time minimizing the chance of misplacing the dongle.

Cons :
Now this is ...

It's okay. A bit small. Wireless worked great as long as there aren't too many obstacles in between. I am writing this after having used it for a year or so (and after finally settling for a dell wired mouse). The scroller started responding weird after about a year.
