Pros: Great LOOKING mouse.

-Can sometimes save previous DPI/color setting. I suggest if you do buy this mouse, that you set the color you want using the DPI button and then manually set the DPI settings in windows and in your games accordingly.

Cons: Bad PERFORMING mouse.

-M1 Button box inside the mouse died after ONE DAY of use. Luckily I have soldering experience and took one from an old laser mouse and soldered it in this ADESSO mouse which fixed THAT problem.

-Sometimes I'll be playing a game and suddenly the mouse will decide to shoot my aim to the top, bottom, or even stay in the regular vertical position of the screen but start spinning really fast 360's. Other times the mouse aim or even pointer in windows desktop will just float to another part of the screen randomly which makes me lose control of the pointer for a few seconds. USB driver changes or updates do not solve this problem.

-Shipping from UPS was horrible. I paid an extra $6 and change for faster shipping and it took twice as long as estimated by UPS and also UPS decided to hold it at their facility near me for 3 days for no reason. I miss the good old days when Fedex was the shipping of choice through newegg.

-Inside the packaging when I got the mouse somehow there was dirt INSIDE the sealed packaging around the DPI button area. Because of this I had to clean the mouse with a dry cloth after taking it out of the packaging. Must have gotten like that during it's packaging at the factory.

-The braided fabric on the mouse cord is not ideal and frays easily. It was even FRAYED right out of the packaging and cord was KINKED as well right where it's connected to the mouse. This is probably due to the poor design of the way it's packaged with the clear plastic sealed packaging/casing.

-Takes a lot to get used to when using it. It's overly heavy in the back side so I took a weight out while I was fixing the button box. The M1&M2 buttons are way too easily clicked even if you very lightly only lay a finger on them which can cause accidental clicks in very many instances. It's a very large size mouse which also takes getting used to. I was actually surprised by it's large size when I got it, larger than any mouse I have seen in person, and I'm a Computer Technician.

Other Thoughts: -There are other computer mice that look EXACTLY like this on Amaazon which leads me to believe that one company made the design and then sold it to many other off-brand/no-name brand company's like ADESSO. Just go to Amaazon and search "computer mice" and you will see for yourself within the first 2 results pages.

-I should have purchased a different mouse from a better/well-known brand like Corsair, Gigabyte, Logitech etc.

-Sad to say but I don't think I'll buy anything ADESSO after this. Hardly anything about this mouse was done well/correctly.

Pros: Beautiful mouse, nice cord, but it is only appearance.

Cons: Terrible quality. Mouse worked fine for about 1 month and it now is worse then "ball" mouses. Optical sensor turned bad all of a sudden.. I never dropped it, nor it has suffered any type of shock nor damage. Quality is extremely terrible... Simply horrible!

Other Thoughts: Don't buy it... unless you dont mind having to rebuy another one later.

Pros: Feels good, nice crispy clicks, looks cool as hell, responsive, adjustable DPI is nice and remembers your last setting when unplugged or shutdown. The cord is a braided fabric, seems very tough and looks good.

Cons: A bit back heavy, not too bad though. The worst con is there is a faint high pitched noise it makes when moved. I assume a hardware design flaw with the frequency of the optical sensor. It is tolerable for me, but quite annoying for some in a quiet room.

Other Thoughts: Overall worth the price if the noise doesn't get to you. Each DPI setting changes the LED color, and the 1600 DPI blue setting is comfortable in most applications for me, and matches my case, so it worked out great. The forward and back buttons protrude a bit aggressively, which could be a con for some. My fat thumb has accidentally hit 'back' a couple times.

Pros: color change, fiber cable, scroll wheel

Cons: none so far

Pros: Its fast, Looks Great, Good feel, Fits my hand nicely

Cons: It has a very high pitch sound when you move the mouse after sitting a few seconds.Its very annoying. If you work station is a quiet one avoid this mouse.
