Razer Viper Ultimate

Hi I just got the Razer Viper Ultimate and have been using it for about a day and already noticed that the middle mouse button wont stay clicked if you try to click it and move the mouse down fast. (seems like a wireless connectivity issue). For the games i play and the keybind i use (MMB) it's frustrating. It also feels as though there's only one button on the right side of the mouse wheel? So when someone presses the MMB with there pointer the apex of it is one the left so your finger naturally forces it to stay down even when you let off the same amount of pressure that you put on.. Anyone else having these issues or maybe my MMB is busted?
