Surface and Materials
The surface coating and side panel materials haven't changed as far as I can tell. The top is a soft-touch matte black coating, and I'm not sure if it features any rubberization or not, but it's great in terms of grippiness. The scroll wheel has a textured rubber surface, so no accidental slips should occur. Both profile buttons are glossy, and the CPI buttons have a metallic design on top, but are made out of a glossy plastic.
Moving to the sides, their main gripping areas feature rubberized panels with a rectangular texture. The texture feels great and pretty much eliminates any chances of losing your grip or accidentally having the mouse slip out of your hands. The side buttons are made out of matte plastic, just like the parts on the sides that don't have the textured rubberization. The front end of the sides is covered in aluminium.
Build Quality
Build quality is just ridiculously good on this mouse, which is as expected given how massive it is. Not a single squeak could be heard from the shell, even when I pressed down on it really hard. Everything is aligned perfectly and nothing rattles inside.
Weight
The wired Ironclaw isn't exactly a lightweight champion at 107 grams, but the wireless version is certainly among the heaviest mice I have ever had the chance to try. It weighs a staggering 133 grams on my scale, which is a lot. The wired Ironclaw was still alright for its size, but the Ironclaw RGB Wireless is just too heavy in my book. While weight is mainly a matter of personal preference, and I know many still prefer heavier mice, your wrists won't thank you for it in the long run if you go for such a heavy mouse. With the battery in the back, it's slightly back heavy, too.
