The reason you don't see cheap mouse here is because of muscle memory. When you start using an input device like a keyboard and a mouse for a long time your brain slowly starts to adapt to it. A terrible mouse will ruin this muscle memory. Make sure you have turned off mouse acceleration for the same reason.

Yes, yes I know about the double click issue very well. The fact is this is the only brand in India giving two years of warranty on the product BUT more importantly a support that works. When your mouse does have the double click issue and you're not willing to fix it yourself with WD-40, you can just ship the mouse to your local service centre and they will repair/replace and send it back for upto two years. This can't be overlooked. Even though there are other competitive mouse like the Razor Deathadder Essential for almost the same or sometimes a cheaper price, the fact is unless you're fine fixing stuff yourself you will end up with a double click mouse in one year only.

Now the mouse has a pretty good sensor for the price that doesn't stop registering when you flick your mouse too hard AND THAT IS IMPORTANT. Most budget "gaming" mouse just don't register your flicks and that's important for a gaming mouse.

If wireless is your main concern and you have gotten used to the G102 mouse shape, this is your main go to mouse without adding a lot of weight and having let go off the hassle.

If you have been using a light mouse (~85gms) then getting this will require a certain learning curve and your aim will be off in competitive FPS games where the flick is important part (AWP Flicks) for a few months AND you will have to increase your sensitivity which will be a pain. Remember this. After I got used to the weight on this mouse I was pretty fine with it during gaming.

Sensor: The main reason to get this over the other cheaper mouse is a better sensor, however I still recommend going with G502 below instead.

Usability: The main thing this mouse has over the others is the extra two buttons on the top left which I mainly use for volume adjustment. The lack of the button just under the scroll wheel really is a shame though.

Usability: Lots of buttons although some mapping require you to run their pathetic software in the background. The scroll wheel on this is the main reason to get it. Once you get used to it, there is no going back.
