Very nice mouse. The size and shape take some getting used to so that you arent accidentally pressing buttons. It is a large mouse and you need big hands. If you want something just as nice, but that fits your hand and natural grip better, Id recommend the VENIX G3012.
Pretty awesome controller conversion kit. Unless parts on your controller are broken, then you dont really need to replace all the parts this comes with (things like the Trigger brackets), but its nice it comes with them just in case.
Pretty awesome little mouse. Functions how you would want it to and fits well in your hand. Only thing I was was different is I would want the USB dongle storage to NOT be inside the battery compartment. As small as it is though I usually just leave it plugged the computer even when transporting it so its not a big issue for me.
