Regardless of color and surface treatment, all Model O mice come in almost exactly the same box. It's thick, very well padded, and has the usual marketing text and technical specifications. Taking a look inside, you will immediately notice that it's very well padded, so the mouse shouldn't suffer any damage during shipping. As for the contents, there's obviously the Model O, a quick-start guide, brochure, and two stickers (one being RGB)—no replacement feet, unfortunately.
This mouse follows a very minimalist, ambidextrous design with side buttons on the left side only, so it will fit right-handed users best. Immediately noticeable is that it's covered with holes—if you suffer from trypophobia, the Model O probably won't be your best friend. The purpose of these hexagonal cutouts is different from those on the previously reviewed Tt eSPORTS Ventus X Optical, which featured a similarly designed back. Glorious' goal was to reduce the weight by as much as possible, which meant taking some material away from the top shell. I will talk more about the weight under the corresponding section.
The Model O's shape is very close to the Zowie FK1, which means it will mostly suit claw and fingertip grippers. It's a relatively long yet narrow mouse with a very low profile. The sides are curved inward to help with a stable grip, which works well as I didn't once lose my grip during testing and some intense gaming. The main buttons feature comfort grooves as well, so your fingers won't slide off and can sit in a more relaxed position.
Moving on to the measurements, the O is 128 mm (4.88") long, which is a bit above average among gaming mice. The total width is 66 mm (2.60"), but depending on your grip style and the attached side panel, the actual width at which it is gripped is about 58 mm (2.28"). Total height is only 37.5 mm (1.48"), and the hump is centered. With these dimensions, I would mainly recommend this mouse to claw and fingertip grippers with hands that are at least 18 cm long, though 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 can, you should always try a mouse before buying it, just to be sure.
