I?m not a gamer or even have a need for switching DPI, but it?s an upgrade from a similarly priced Logitech. Works on an iMac. Does everything I need it to. Nice quality.

Very nice looking, comfortable in the hand, no lag. The only con is the cord is heavy and there is alot of it ... if pulls on the mouse is hanging off a table... you need to velcro it up to take off some of the weight.

this is my second mouse and this one, which was bought for me as a xmas gift, does not "light" up like the one that I bought myself by in early November. I will include two photos that show the only part that lights up is in the very center of the light bar. If I move the mouse it lights up, but when just sitting on the pad, nothing. that is not how my previous one works. It is constantly lit up all the time. very disappointed. Only second time that I received a bad product from Monoprice. Please explain what you are going to do.
Thank you, Dan S

i don't have a video to show exactly what i mean but I can still describe it, the led light don't work I press the button to change the solid color but it blinks three time then the light cuts off the time it turns on is when I move the mouse it self but besides that the multi color changing doesn't happen.

very good purchase at the sale price for a stylish mouse that works well and has smooth operation and satin finish on it. hope it will last a long time.

Three principal buttons work as they should. There are no instructions about the two extra buttons, which I would like to use for copy and paste.
(One returns you to previous screen; I have not found out what the other does.) My other mice have all been programmable with Steermouse, but this one is not. The mouse is of no use to me, and I will return it.

Disclaimer: Monoprice lent me this product to try in exchange for a fair and honest review

The Dark Matter Rover is a perfect entry level mouse if you are looking for better optical reaction in your control but do not need extra buttons for specific gaming needs. I use this mouse at work to give me better precision while working on digital drawings. A typical mouse will have me fighting to get to that exact spot I need to be, but the sensors on this one are accurate and never leave me questioning if I can draw something correctly on the first try. This is a great mouse for the price and I have no issues with it.

The mouse will not stop at any of the color/dpi settings. It just keeps cycling through the colors. Very frustrating. No help from support.
