I've bought this mouse on February 21st 2020, and today (April 11th 2020) which are not even two months later, I got a very odd problem with it. I was not able to drag and drop files into a folder, move objects on my desktop or keep shooting at things in videogames. I then tested under paint to see if there was a problem. And found out that the left mouse click was not holding down while I keep pushing on the button. So I dug a bit on google and found out that it is a very common problem with this particular model. It is simply the switch that needs to be replaced. But I cannot understand why it prematurely broke like that. With the help of a few online videos showing how to replace it, I repaired it very quickly with my soldering station. Fortunately I had some spare parts lying around. I know that voided its warranty, but I know what I'm doing. And it's working properly now.
Beside that matter, the mouse are really responsive. I have a very high refresh rate on my monitor, and the cursor moves more smootly compared to my older mouse a decade old. When I opened it, I saw that the battery inside are way more smaller than I thought. But the battery life are good and can hold two weeks before recharging it. Ive disabled the RGB lights because I really don't like that feature.
