Pros: -Great right hand only mouse.
-Optical Laser
-3 dpi settings and the click of a button, turns red, green, and blue respectively
-Durable, braided cable plus excellent build quality

Cons: -There lowest tier Naos so it doesn't have the led control and custom dpi control
-Some might find the blue led (3200 dpi) too bright

Other Thoughts: I had this mouse for almost 2 years now and will be buying the 7000 version after this one starts to go, which at this rate will be a very long time.

Pros: Great Design and comfort.

I owned an Naos 8200 which I thought was great and led me to buy this mouse. Sadly I didn't get to use it for very long to list additional Pros before it stopped working.

Cons: Malfunctioned within 5-10 minutes while playing CSGO. Made a weird noise and all the lights went out and the mouse was completely dead. Obviously I am very disappointed, especially since I have to pay $8.99 to return this defective product and wait an eternity for a replacement. Ridiculous.

Other Thoughts: I sent in an RMA for for a replacement. I probably should have just gotten a refund, but I believe in second chances. Hopefully the replacement works out better and I don't have to pay an additional $8.99 to return it. :(

Pros: fits the hand well, the pinky rest is a feature i didnt know i needed.

Cons: having a smaller hand, i find the mouse buttons by the thumb a bit too big. cord is a bit kinky at the beginning, might straighten out with time

Pros: 1) Great right handed palm grip. Fits like a glove
2) Red, Blue and Green LED color options that can be changed easily so your favorite is matched up with you most used DPI setting 800, 1600 or 3200.
3) High quality coating and cable
4) Relatively inexpensive for a gaming mouse.
5) Has great tracking on my cloth pad
6) Programmable buttons with macros

Cons: No major flaws, just a few small things. The cable is a little stiff. It isn't the best sensor you can get (although its still a good one for the price). Each DPI setting has to have a different color, so if you switch often in a game, you end up playing with a color that might not match your other stuff (I know its nit picking). Lastly, the mouse can be hard to pick up for some people, so if you do that it might not be the mouse for you.

Other Thoughts: I LOVE the shape of this mouse. I'm a full on palm grip and I've never held a better mouse. It's a nice clean design with 7 buttons. I know some people like more, but thats more than enough for me.

Pros: My large hands make most mice uncomfortable, but this one fits like a glove

Very responsive and accurate

Long braided wire

Matte black looks very clean and nice compared to many flashy looking gaming mice

LEDs are tasteful and indicate dpi setting

Pleasant texture

Cons: Braided wire wears quickly against rough edges

Like most mice, can start double-clicking on single click after a couple years regular use.
I fixed this by poking around inside it and cleaning it a bit, but this mouse is not made to be opened easily; I had to crack the shell open, leaving a hole, to remove the shell and expose the insides.

Difficult to clean thoroughly because difficult to open

Surface eventually gets tacky feeling with regular use, like most mice, but lasts longer than other mice I've used.

Other Thoughts: While other mice in this series are "better" this one suffices my needs and has become my mouse of choice.
I recently purchased a second. My first has seen regular use for nearly 3 years, and still works well, but the cord is worn, the surface has gotten tacky and I put a hole in it.
It's one of only a couple mice I've used that fits my hand comfortably; small mice make my hand cramp.

I'd gladly buy another again in 3 more years, if needed.

Pros: -Extremely comfortable
-ZERO fatigue even after a few hours of gaming
-Easy DPI shifting
-Braided cable
-Accurate tracking
-No over-the-top "gamer" aesthetics! That's a big one for me.
-Satisfying click
-Good build quality and finish

Cons: -Mouse wheel frequently clicks while scrolling
-Side buttons press too easily: I EVEN ACCIDENTALLY WENT BACK A PAGE WHEN WRITING THIS REVIEW! FRUSTRATING!
-Doesn't perfectly fit my hand (although these are minor complaints)
-Could be longer
-Could be slightly taller
-Software is extremely lacking
-Only three color options
-It may be light for some, but I became comfortable with it very quickly
-Doesn't work on white surfaces
-A bit difficult to pick up while gaming

Other Thoughts: -I switched from a Cooler Master Recon and could never go back!
-I may have a long list of cons, but I highly recommend this mouse, especially for the price!
-3200 DPI is more than enough
-With a few revisions this could be the perfect mouse!

Pros: I was hesitant to buy a mouse this expensive, but after having used it, I would buy it again in a heartbeat. It is the most comfortable mouse I've used. The size and shape are great. The mouse wheel is perfect: good scrolling and easy to click, unlike my previous Microsoft mouse that almost hurt my finger. The other buttons are easy to press too, and the back and forward buttons are the right place. I like that the mouse is corded, so no more replacing batteries every few months.

Cons: None, really.

When I opened the mouse, there was a small piece of broken plastic stuck under the left mouse button. Since I could still click (just had to press harder), it took me a day to realize it wasn't made that way. Two minutes with a paperclip, and I got the broken plastic out.

Other Thoughts: My previous Microsoft mouse had a similar rubber coating that after a few years turned somewhat sticky and got covered in unremovable dirt. I've worried that will happen with this mouse, but I've owned it for 2.5 years, and it is still fine. The coating does feel great.

Pros: Had this mouse for a couple years and it's still going strong. Great feel when in use, very responsive, hasn't broken down once.

Cons: Above

Other Thoughts: The cable frayed a little bit, but that was mostly due to rubbing against monitor stand. Would purchase again.

Pros: I like the feel of the mouse. I also liked the Naos drivers.

Cons: Thumb buttons, scroll wheel button work intermittently after 5-6 months of average use. Thumb buttons are too far forward for my average size hands.

Other Thoughts: I purchased Naos propus 380 mouse pad thinking they work well together. Nope, grainy feel when sliding the mouse.

Pros: I love this mouse. Fits my hand. Smooth action.

Cons: None what so ever!!!
