How to open up iogear's Kaliber Gaming Retikal Pro FPS Gaming Mouse?

How to open up iogear's Kaliber Gaming Retikal Pro FPS Gaming Mouse? I can’t find any way to open this kind of mouse. My mouse wheel doesn’t scroll and I feel like I could repair it but I have absolutely no clue how to open this up. Screws are nowhere to be found. I’d have to have to send it to be fixed via warranty or buy a new one altogether.
