I bought the Salmosa recently and i'm simply shocked at how bad quality it is. Its made of the cheapest lightest plastic shit, the buttons are squeaky, I just can't believe nobody has mentioned this before? The buttons are not only squeaky, they are kind of unresponsive as a result of it. If you want to make the mouse any cheaper you should basicly make it out of paper or cardboard. I dont hate razer, I like the diamondback although the button durability is low. And I like the Death Adder, it has good buttons. If anyone at razer reads this: Please make the durability and buttons of your mice a higher priority.
