Pros: Out of all the mice i've had in the past this defiantly lives up to my expectations, and then some. I've had this product for a while, and it has not once given me any troubles, works great for mmo rpg,and Fps games. and a year plus later, it still works as if it just came out the box. so you need something under 80 bucks to game with, this is your mouse.

Cons: None

Other Thoughts: The only other thought is why didn't I buy this sooner then i did, I was actually really skeptical about it when i brought this mouse, and told myself that if it didn't work like i wanted it to or didn't last like i hoped then i wouldn't worry about buying this particular brand any more. but from day one i was very satisfied with this mouse and the keyboard that i got from Gx gaming. would Highly recommend Genius Gx gaming to anyone who games.

Pros: great looking, very quick response, big enough for my massive hands. great customization weights are amazing.

Cons: after about a year of constant use, im having an issue with it double clicking everything. when i click something it will double click it for me. its very frustrating trying to play very click heavy games, starcraft, smite, magic.
holding down the mouse button doesnt work all the time either. maybe its wear and tear.

Other Thoughts: i love this mouse and im planning on buying another one even after the issues i had with it after a year.

Pros: 5 DPI settings allowing for flexibility, adjustable weight, fits comfortably in my medium sized hand, and is very responsive but doesn't exaggerate sensitivity either. The customizable light color and breathing times was a nice touch.

Cons: None

Pros: -Accurate. No wobbles or random travel of cursor
-Sensor on it is sharp
-Great fit for fingertip grip
-Great DPI range

Got this mouse on a bit of a random cast of the dice on mice. Previous mouse is a Logitech G9x and it's been slowly dying, so got this to replace it after trying a LOT of mice. GREAT shape for a fintertip style grip (or claw), especially if you have a large hand (I have a large hand with slender fingers, my fingertips hang over the edge of most mice if I try to palm grip). Also, it's a wired mouse, which means no surprise wireless failures in the middle of gaming.
Really pleasantly surprised.

Cons: DPI switch is single button, "one-way". You can change DPI, going higher only and then starting back at lowest DPI. The G9x has me spoiled.

Other Thoughts: Haven't tried macros on any of the additional buttons. Can't speak to their function. The layout on them is not that bad though. My key things for mice are: 1) friendly grip for me 2) accurate - no drift or travel with cursor (burn Razer!). 3) DPI adjustment 4) Wired 5) scroll wheel is responsive

Pros: Looks great. Finally something with a nice fit for a person with a big hand, with long fingers who uses a fingertip grip!

Cons: I can sit and watch my cursor wobble. Leaving the mouse sit on the desk, with no outside vibration or movement sources, sitting on various surfaces, and the cursor is doing this little jig across the computer screen. Just this little wobble, as it slowly dances in one spot, or wanders a little bit off in what seems a random direction. Not thrilled about this. This is the same reason I refuse to buy Razer's junk.

Other Thoughts: Going to give it another day or so, try tweaking it, alternate mouse pad, reload driver/software again, see if that fixes. If it doesn't, it'll be RMA time with a more comprehensive update here.

2 Eggs as a warning shot.

Pros: - Good looking
- Cheap
- Responsive

Cons: - A little big

Other Thoughts: I come from a ball mouse that I used for 10 years. I gamed a lot with it at a good level and just didn't want to make the switch to a newer and more gaming oriented mouse.

I was looking at gaming mouses for a while and I saw this mouse on sale at 40 something $. I went for it and don't regret it. It looks good, its not expensive.

The only thing is I need to get used to it big time. I spent about an hour adjusting mouse speed, sensitivity and dpi (3 of which affect mouse speed) until I reached something close to what I had. I was clumsy with it at first but after a week, I'm starting to get the hang of it. It's a little big and I'm not sure I'll be comfortable with it to the point of getting back the reflex speed and pointing precision I had but I needed to try it out.

Some of you might have a problem making light change color. Mine stayed on red even if I changed it in the software. I messaged Genius about it and they told me to uninstall the CD software and go with this one :

It works fine now.

Frankly, I don't get how people need more than 3000ish dpi. I am at 6/10 mouse speed, 6/10 sensitivity and 2500 dpi and I am scrolling from one side of my 24'' screen to the other with a medium flick of the wrist. I know some people game with greater sensitivity but going full sensitivity with this one, plus full ingame sensitivity, is plain silly.

Pros: For the price, this mouse delivers, I'm happy with the feel the accuracy, and the amount and placement of buttons.

The RBG lights are cool, and the Weight changeability is not a feature that I expected at this price range.

Additionally, the price is a good match to the quality of this product, you get what you pay for, nothing less.

Cons: The ONLY con I can think of, is that it stores an uneven amount of DPI presets (5), this makes it impossible to make it behave like a precision aim mode, because there has to be a repeat in the loop, Example: 2600 > 1300 > 2600 > 1300 > 2600, Two 2600's in a row.

Other Thoughts: Nothing else to say, Good price Good product, simple as that.

Pros: As any consumer and gamer, I was a little skeptical about buying this mouse due to the lack of information and reviews on it. But I took my chances, as I had a really good feeling about what I was getting myself into.
Got it overnight with the 2-day shipping (free) trial thing. Plugged it in, installed the driver; fell in love with it. The ergonomic feel is perfect. It even has this little ledge on the right side where I keep my right ring finger clawed onto. It also comes with six 4.5 gram weights.
As for the driver itself, it's got a lot too offer; in fact, a little too much. Macros, in depth dpi/sensitivity settings, and even the color of the light on the mouse. Every single key on the mouse is programmable, as well. Although you don't have the option to bind them to actual keys on the keyboard, I got around it by attaching a macro to the button, and programming the macro to be a specific button press. (example; macro1 would press F12, and then I'd assign "dpi +" as macro1, resulting in an F12 button press.)
The mouse movement itself is unbelievably accurate. I haven't tried it on any FPS games though. The mouse also comes with 5 programmable profiles, and can be switched between using the DPI profile switcher in the center of the mouse. The macro manager in the software also allows you to record key + mouse clicks and play them back whenever you choose to, but I haven't found any need for that as of now.

Cons: The top compartment plate for the added weights is a little annoying since it's held down via magnet. Every time I put my hand on it, it pushes down a TINY bit. Afterward, there's no problem past that.

Other Thoughts: If you're an MMO gamer like myself, and you need those extra mouse buttons, then this is the mouse for you. Every button is placed in easy to access spots, so no need to have your fingers wandering around looking for em.
[IMPORTANT NOTE]
For those of you who are wondering like I was...
Every individual button is programmable to ANYTHING you desire. That is 11 programmable buttons in total. Left click, right click, middle, up scroll, down scroll, 'macro', X, Y, button 4 (back), button 5 (forward), and even the DPI profile switch button itself.
Overall, I'm extremely satisfied with my purchase, and would certainly recommend this to my friends.

I will be posting another review in a couple months to see how well it lasts.
