Pros-
This is exactly the same as the Logitech's mx518 except the design.
Excellent features.

Cons-
Could have been a little cheaper./ Slightly overpriced

Great mouse for those who prefer a palm grip.Comfortable and Ergonomic.Personally i feel that under 2000 u cant get anything better!!!

Its a good gaming mouse under decent price. At this price I guess this is the best I can get. And the most important thing is that have a DPI of 4000 which is one of its kind at this range.

The first time I received a faulty piece and asked flipkart for replacement. But because they didn't have it in stock, they told me that they would refund the amount. But after 3 days the mouse was again back in stock, and they cancelled the refund request and placed a replacement request. Very good follow up by Flipkart. Kudos! Received the product. No problems. The clicks are very good and the driver software is also equally good.
I had a Razer death adder earlier. I would recommend any new...

my son bought it and he loves it. especially the dpi changes and the ability to assign buttons to keys.

Flawless sensor. Decent build quality. USB disconnection also fixed compared to G400. 10/10 would buy again.

Awesome gadget :) This was my first gaming mouse. So obviously there will be a great difference when you change from using a normal mouse to a gaming mouse. The advantage i felt over this mouse is that, this mouse perfectly fits in my hands. The grip was great to hold. The main advantage i felt was its accuracy. I usually play counter strike. When i was using the normal mouse the average score would be frags-25;death-10, But now frags-25; death-3.

i bought this mouse after 4days research and decided to buy this after using this mouse awesome experience this was my first gaming mouse.

go for it Logitech rocks

this is one of the best mouse i have came across...
formerly i have used steelseries kinzu v2....steelseries kana...even razer death adder....but this takes rifling to a next level...especially in counter strike...
awesome grip...very good trackers...and sensors...smooth buttons...and easy handling...
using it on steelseries qck mousepad...and this mouse does wonders,....
on-the-fly cpi increase and decrease buttons...
smooth and very efficient...
in short
pros-
1- great grip and smoothness
2...

This is a very good and an ergonomically well-designed mouse. Since I am a heavy user, I wanted a mouse that would provide me with a natural palm-like grip. This mouse fulfills that want. Also, the size is large enough.
