cheap and fragile

The two side buttons are extremely fragile. Mine are broken after 4 months of use gaming frankly not intensive .. The mouse is NOT guaranteed, it is therefore of no use to me.
Of course, I expected an unreliable product considering the price. 2 or 3 years of life was not bad. But it was four months ... the calculation is fast, it is better to buy a more expensive mice that will last for years, I remember the lesson :)
I would add that the two main clicks are too hard, those who play shooting games will go through cramps to the index.
Double click the button is ergonomically fear and difficult to use.
