Amazing mouse even for big hands.
Color: White
So I have big hands and what any big hand gamer understands is that you either have to get a big ol heavy G502 size mouse or use a certain grip to hold all these mice for smaller handed people. I previously owned a Model O, G pro, and Model O wireless. Having big hands my biggest peeve with all the other mice is that they’re ambidextrous mice so they are even harder to hold with fingertip/claw grips because the smooth, near flat, symmetrical sides. I only really make contact with the sides by pinching my fingers with them. I never make contact with the butt or base of the mouse with my grip. There’s where the Orochi changes things The Orochi somehow is a smaller mouse than all of the above but fills out my hand and grip SO much better. The sides actually have slight grooves so I don’t slip off the sides of my mouse and the shorter but bigger hump in the middle makes me for once actually feel the mouse in my palm if I want. Overall the feel is amazing. Battery life varies of course but I can barely tell there’s a battery in the thing even when flicking and the weight and balance of it feel so good. Mobile gaming is the main reason I got this mouse. I like that the dongle stores inside the mouse, uses batteries so I don’t have to worry about keeping it charged or bringing around extra cables to charge it, and the Bluetooth is good for casual gaming but doesn’t do great with big flicks so the 2.4ghz connection is required for esports games. Overall a great mouse and really awesome to game with and a little plus to it is that the shell comes off the back so satisfying, it’s hard to not fidget with it by taking it on and off haha. Well worth the money and I’d expect they’ll make a rechargeable one with all the success this mouse has accrued so far so if the swappable batteries don’t tickle your pickle, I’d just buy a sub $20 rechargeable battery station or just wait for a new rechargeable Orochi to come out.

Great quick mouse <3
Color: White
Very nice mouse though the scroll wheel is a little hard but it doesn’t skip around or behave oddly. instant set up and very comfy! I’m a girl with small hands so it fit perfectly! not too big or uncomfy, I can naturally grip it and the color is so perfect for my pastel blue and white setup! The click is a bit loud but not annoyingly loud, feels very sturdy despite it being so light, I’d say it’s a good price for a gaming mouse! (no connection issues either with Mac) I don’t have a mouse pad and it actually glides pretty good on my wooden desk.
