Pros: Looks good. Can customize to fit hand. Keeps lots of statistics if you care about how many times you've pressed each button (I don't). Allows six profiles if you care (I don't). Lots of other settings available such as sound, timer, etc.

Cons: Poor quality in consistency of mouse. Each button has a different strength requirement, e.g., the right button requires more force than the left button. The right side buttons with default side panels activate when brushed, the left side buttons require a firm push. Can program six buttons but two of the eight buttons aren't customizable (DPI and scroll wheel)

Other Thoughts: Not a gamer but wanted a programmable multi-button mouse for features like zoom it/out, back/forward, close application, etc. Ran out of buttons after six so couldn't add what I wanted.Would like to have programmed DPI setting button (which I don't trip accidentally) or scroll wheel button. With the default side panels, the lightest brush against the right side buttons, which happens frequently, trigger them so constantly zooming in/out when undesired. This went away when I changed to the smallest side panels. Didn't try the largest side panels since the medium ones were too large for my large hand (personal choice). This is an obvious copy of an "R..." brand mouse which is made in Czechoslovakia but without the quality or consistency. It's mandatory that you download the software (not included in package) because one button only takes you to their website and another changes profiles that you need the SW to set. There is no way to change the tactile feel of buttons in total, much less individually, to make them harder or softer to push. The software itself is poorly designed and loses settings randomly, I've had to restore a few key assignments multiple times.
In summary, if I had the choice to buy it again, I wouldn't.

Pros: Nice weight. Not too light, not too heavy
Buttons! 7 + 1 DPI switch
Multiple profiles, I believe 8
Many color options for the mouse wheel lighting
Different clip-on options for the sides of the mouse, different feels/aethstetics for different people
Stickers
Laced cord

Cons: The logo is very prominent and cannot be turned off, but then again it will hide under your hand while it is not used.

Pros: Fantastic gaming mouse at a great price. I just wanted to write a review to give my opinion on the DPI button for this mouse. Several of the comments have said that this button is placed so that your hand inadvertently clicks it while resting on the mouse. This is not true. The DPI button is placed between your fore and ring fingers and I don't see how these people are having problems. This is the first mouse I've had with a DPI on it and I love it. Also, I got it for 19.99 as a shell shocker deal and for that price I'm extremely pleased.

Cons: none that I can tell

Pros: Customizable, it works.

Cons: The left click button broke, contacted Gamdias customer service and got absolutely no response. I'm still waiting. It has been over six months...

Other Thoughts: If you get a mouse that lasts, good for you. For $20, it is not a bad deal but don't hold your breath if your mouse breaks.

Pros: Updating my previous review. The initial flaws of the mouse still exists but it's good to know that the customer support team is willing to help you ensure the mouse works. The have a working fix for the firmware problem with the mouse. I am just uncertain as to why the download is publicly shown on the website

Cons: Same as before.

Other Thoughts: See my other review, but now I don't feel bad about buying the mouse. I wouldn't recommend the mouse to other people, but since I already own it, I do enjoy using it.

Pros: The mouse looks spectacular and feels nice in your hand.

Cons: So many things plague this mouse. The first concern is that the button to change the DPI is located directly next to where your fingers rest. Nearly every time I'm playing a high action game and things get exciting my fingers accidentally hit the DPI button causing the mouse to spas over the screen at in opportunistic moments.

The support for the mouse is awful. I don't believe Gamdias even cares about you after you purchased their product. When you download the program to customize the buttons they even spelled the name of their products wrong on the program.

Speaking of downloading the support program for the mouse... DO NOT DOWNLOAD THE SUPPORT PROGRAM. Other than being poorly coded, the program prompted me to update the and then proceeded to crash the hardware of the mouse and now the mouse is completely nonfunctional. I read the reviews and saw this was an issue for other people, and I thought that that would just be a freak occurrence--however it seems to be a pretty consistent bug.

Anyways the mouse doesn't work now, and when the mouse did work the sporadic nature of the DPI button is super annoying. Save up a few bucks and browse for a different mouse.

Other Thoughts: The mouse looks cool at least.

Pros: It looks just like a real mouse. You can disable most of the things that make terrible, rendering it just like a regular mouse.

Cons: All of them. More specifically:

-DPI resolution button right where you rest your hand so it changes whenever you lean your hand down a little (changes how fast your pointer moves).

-The "support" software was abysmal. When I finally found it and downloaded it, I was able to disable the button that, when misclicked, takes you to Gamdias' website. Right to the website, regardless of what you are doing... You can use the website to try to figure out how to fix the mouse, but how to fix it is not listed anywhere on the website...

Other Thoughts: If you love someone, do not let them buy this mouse.

Pros: well made and programmable.
more quality than i expected for the price.
feels like a more expensive mouse.

Cons: none at all

Pros: the mouse itself is very well built and comfortable in hand.
the with of the mouse can be changed by swapping the plastic spacers on the side.

Cons: the first thing is that there is no installer cd in the box, they tell you to go to the website and download it, a mild inconvenience.

the zip file that is downloaded is the raw program, no installer.

the program itself is buggy and needs improving, but i did revive an update so i think they are working on it.

Pros: - Presentation as nice
- Wire is durable and not cheaply made
- Mouse has many ways to form fit your hand
- Price
- Graphic interface software (This software allows you to set macros, hot-button tracking, to timers on your mouse. Its so in-depth with its over the top program-ability the detail rivals that of Logitech with half of the cost.)

Cons: - You cannot switch the color of the yellow GAMDIAS logo which I could care less since my had covers it. So not a con to me, maybe to you.
- Exe start up file instead of having to unzip. However thats really nit picking it.
- Something to put the extra parts in but again I am nit picking not a necessity.

Other Thoughts: Really unexpected quality from such a low price point. Its software is advanced so will take some getting use to but everything you need is there. Ooo ya its ambidextrous so has that going for it as well.
