I second that, I'm using one atm. You'll need to have a 'claw' type of grip to reach all the buttons easily. Its kinda huge and uncomfortable for long hours of play, my hands are actually quite big already (I can lift a basketball with just one hand) and I still find it uncomfortable. The laser used goes crazy once in awhile and I need to unplug and replug it. Imo, its not worth it. My previous razer, the Diamondback beats the cr@p out of my current Lachesis. Don't get me wrong, I like Razer, in fact I just imported a Razer Nostromo during Christmas but the Lachesis really needs work, it should be much better for the price it commands
