After 1.5 years of usage, I can say that this mouse is very good.
It is a little smaller. But the shape is very good and comfortable to move around. The body is entirely made of plastic. It is not glossy. Happy how it feels in the hand. Not suitable for bigger hands though. Over time is can get small scratches. But they are absolutely not noticable unless held very close.
The buttons are clicky and very responsive. The scroll wheel is smooth and pretty accurate. (Personally, Not had much use ...

its pretty good product if you use laptop daily basis and you want some quick moves 😉

I'm writing after a few months of use. Battery lasted for more than 6 months. Pretty smooth working. Also easy to hold and use. Used it for gaming too and experienced no issues.. I'm satisfied and I do recommend it.

I rated 3 stars because it sometimes does not work.
Everytime I open my PC, I have to remove its USB and plug it again. If I don't do so, the mouse will not work. It is also small in size.

The best mouse

Nice Mouse

The battery holder is accessible from the top and the top plastic cover isn't great quality. However, the mouse is very good.

I m very happy with this product

Awesome product, am satisfied after buying this product and its more comfortable to use easily and am using this product since two month but ME have no need to faced any problem related this problem till now..

It compliments the Dell laptop it is paired with. Smooth operations and trouble free click. Works on various surface as well. Using it for office and general purposes, and not gaming. Being Dell branded, it is a bit more expensive than other mouses, but the build and feel of the mouse inspires confidence on long term reliability.
Being a new purchase (a couple of weeks now), i cannot comment on battery life usage.
