The Glaive RGB Pro packaging is nearly identical to the previously reviewed Ironclaw's, which means it comes in a chunky, yellow and black cardboard box without any windows. Its contents are the mouse, two different side panels, and three guide booklets. Unfortunately, there are no replacement mouse feet in the package.
Shape
When it comes to shape, the Glaive follows a design that looks a tad more complex than it really is. There are some ledges, cutouts, and other parts that break its consistency visually, but it's just a really well designed, smooth mouse that feels right in the hands. It's clearly not a small model and built for right-handed users, mostly those who prefer using their mouse in a palm grip. I felt that it was slightly too big for my 18 cm hands, but I really prefer smaller mice. I think it could be used with 17 cm hands at the minimum comfortably, but comfort is a matter of personal preference.
While both sides are narrower at the top than the bottom, the mouse has the right curves to provide enough grip for picking it up easily. The right side is slanted, but its front-end has a mostly straight edge I found particularly helpful with maintaining a stable grip on that area. The main buttons feature the usual slight comfort grooves that can help your fingers settle into a more relaxed position.
Let's see some measurements! The Glaive RGB Pro is 124.9 mm (4.88") long, which is about average for gaming mice. The total width is 68.5 mm (2.70"), but depending on your grip style and the attached side panel, the actual width at which it is gripped varies from 62 to 65 mm—we're talking about a wide gaming mouse here. The total height is 45.5 mm, and the hump is centered. With these dimensions, I would mainly recommend this mouse to palm grippers with hands that are at least 17 cm long, although it can work with different grip styles and hand sizes outside of those parameters as well—it's all a matter of personal preference. If you have the opportunity, always try a mouse before buying it, just to be sure.
Here are a few extra pictures of the mouse:
Modularity
As mentioned before, this mouse features a modular left side you can attach three different panels to. These are held in steadily and sturdily with magnets. The default panel is basic—slightly curved and nearly straight; I found it to be perfect for me. The second panel is wider and has its front end stick out more. As for the last one, it features a full thumb grip and also has a mouse skate on its bottom, so it won't scrape up your mouse pad. All three panels feature a rugged, textured rubberization that helps a ton with the gripping experience.
