Runsen Adjustable Length Gaming Mouse 4000 DPI 10 Buttons Optical Wired Professional Mechanical Game Mice Support Macro Programming(RGB Led lights) (Gray)

REASON FOR MY PURCHASE: Wired devices DO NOT produce EMF radiation (Electric and magnetic fields) that can be measured by devices. So if you still use Wireless Mouse or Wireless Keyboard - be aware that wired mouse and wired keyboard is much healthier alternative for your long term computer use.I haven't been this happy in a long time. Seller of this product is great. This mouse is fantastic. I love it. Excellent buy. It says DPI is 4000 but the most I could squeeze out of it in my computer win 10 is 3500 DPI, but still it has outstanding performance. I was a bit scared at first when I connected this mouse to my computer because it was super uncomfortable, but then I figured out there there is a button under this mouse that if you click it adjusts itself for faster and lighter use. So if you happen to have the same issue - remember there is a small adjustment button that you can click with your pen or pencil, and also adjust DPI settings on the mouse and on your computer by Installing CD that comes with this mouse.

For the first 20 minutes of using the mouse, I loved it, but then it just died on me. I was playing a game to test it out, and it worked fine. The moment I exited the game, the light on the bottom of the mouse shut off. It became unresponsive to movements and clicks. I was unable to turn the decorative light off, so it remains as the only thing operational with this mouse.Instructions are all in a foreign language, so completely unreadable.The mouse comes with software which includes two applications and a .doc file. The first application I still have no idea what it does, never worked. It requires the mouse to be plugged in, but it could never detect it. The second application worked fine, but when the mouse failed, the application couldn't even the change the color of the light. The .doc file produced an error message everytime I tried to open it.For nearly $30, I expected something that would last way longer than a hour. Very disappointing.

It’s a really nice mouse. However the wire is slightly, and I mean slightly frayed. But otherwise it’s a great mouse, live the metal feel.

I bought this mouse almost exactly 3 months ago, and as other reviewer said happened to them, it just stopped working. I've plugged it into 2 other computers to confirm and only the top LED lights turn and the scroll wheel works, but that is it. It was nice while it lasted but absolutely not worth the buy.

I love this mouse, it looks awesome. I love its metal material and mechanical-like feel, which is really cool. It fells smooth and is very comfortable, and its size also fit on my hand very well. It is very cheap for this price with such a high performance! I would recommend it to my friends.

This is the best mouse I've ever owned. It has a medium weight, just enough for me to swing around while playing games without wearing out my wrist. The fully extended length is perfect for my (large) hand and my little brother can even use it without any problems. Very responsive over 2000 DPI. Excellent software that comes on the disk, allows for several color and DPI customizations. Also has a cool magnetic, detachable palm rest covering the adjustment screw (also makes a good place to store the supplied hex wrench).

Cool product, but after a month it just stopped working. I haven't had time to return it which is a bummer and I tried to contact the company about this issue but they haven't responded...

Great mouse, a little narrow but I just have big hands. The mouse is on par or even a little bit more better built than the standard brand name pc gaming mice. Its leagues better than non-brand name mice you find on this site.
