How the hell do I open my weight tray

[K.I.L.E.R]

I have a G15 keyboard(with LCD screen on it) and a new G5 Logitech mouse. I also bought a Pioneer 110D DVD-RW.
Excellent products.

Anyway I would like to know how to open the mouse's weight holder.
It's a metal thing holding the mouse's weights.
I can't get the bloody thing open.

Thanks.

I got it open.
I used a knife.
