Zalman 4K DPI USB Gaming Mouse Bilateral Design for Both Hands (ZM-M600R)

Best mouse I have ever used. I have bought many mice including from SteelSeries: Sensei RAW frost blue, Sensei RAW rubberized, Rival White, Rival Black. Razer: Deathadder Chroma, Deathadder 2013, Ouroboros. Corsair: Sabre RGB, M65 RGB. Logitech: G402, G303, G502, G700S.The clicks are very fast, not so light that you accidentally click it. The sensor is very good, tracks flawlessly, no mouse acceleration. I mainly play FPS games with this mouse. Convenient toggle buttons on the bottom of the mouse for polling rates and mouse dpi. build quality is pretty good, but i would wish the mouse was slightly larger and more rubberized for better grip. Cable is not too stiff that it blocks your mouse movements and there is an added bonus of RGB lighting for logo and scroll wheel. Lift off distance is around 2mm or so.

NOTE: This review is for the ZM-M501R, since Amazon insists on grouping dissimilar products together, and it's not always obvious which one the review is for.First, I'll just say that this mouse works great, and looks pretty sharp as well. I have no real problems with it functionally. However, I do have something against it -- it seems to produce a lot of electrical noise. If you have front USB ports and one is near the front headphone jack, it sometimes tells you just how noisy a device is. I expected the ferrite to handle much of that, but apparently not. I got this because I had a Microsoft IntelliMouse which was causing an annoying hiss on the headphones, and replaced it with this, and... well, it's MUCH worse, and pulses in and out. I thought it might have to do with the lighting of the mouse, but the two aren't coincident (the sound goes in and out a few times each time the light fades in and out), so I'm not sure exactly what the deal is.Anyway, if you don't care about that, the mouse is great for those of us with large hands, like me. I like how it feels, and I like how it glides across my desk with little effort. It seems to work really, really well. The DPI settings also seem to do what they say (I leave mine at the blue 1000dpi setting). So for now, I'm happy with it, but keep it away from anything that's noise-sensitive.

The WORST switches ever put into a mouse! Great finish, glides extra smooth, feels great in your hand.......and after using it for about 10 minutes, your finger is so sore from the extreme amount force it takes to click the button, this mouse is a joke.....don;t know what they were thinking?

Google "mouse click latencies" and you will find a chart that shows that this is one of the very fastest mice when it comes to responding to your button presses. It is shameful how other mice add significant delay to presses due to crappy firmware or inadequate micro processors which cannot turnover fast enough for proper response. 500 or 1000mhz polling does you no good if your mouse is only truly updating its state 50 times per second. Do you want a mouse that takes 20ms to register your clicks? Buy something else. Do you want it to take 5ms to 10ms? Buy a Logitech or Razer. Otherwise, buy this.I like the shape. The weight is too much, but if you know how to use a screw driver you can remove the cover (single screw hidden under bottom rear Teflon). I recommend piercing the Teflon rather than removing it, since you'll add a shape to it which won't go away fully when you reapply it.The only real problem with this mouse is the lift off distance which is very high. You can address that by putting your own super thick Teflon feet (like 1/8th of an inch) on the bottom, otherwise you're going to be a little disappointed by the extra motion you get when repositioning the mouse on your pad.

like the last reviewer, i only had this mouse for a few months before the scroll wheel broke. its cheap tho so no real loss there

The build quality is good, nice shape, decent cable and weight. The 3090 sensor is very capable with the tape trick to reduce the LOD. Just remember to turn off angle snapping with the software because it's on by default.

Using this mouse to rapid fire in Battlefront. Works great for that via the ultra low click latency. It is a small mouse and can be a little fatiguing depending on your grip. I am using this mouse almost exclusively now and I have a fairly large collection of gaming mice at this point. My second fave is, strangely, my old Razer Imperator. I can rapid fire pretty good with it as well. I am able to aim pretty accurately [for me] with this mouse and recommend it for frenetic action. Mice are very subjective though so YMMV. For the price it seems like a safe buy. Quality seems fine to me but time will tell.

This works fine for me as it is a little smaller than most mouses. It fits my hand better. Has all the buttons I need for gaming (not a power gamer) and this is my 2nd of the exact same mouse, I got it for a new comp and kept the old mouse on a different comp.

Good product to replace my worn down mouse. Order arrived sooner than estimated date.

before using this mouse wipe down with a damp cloth as if you don't your hand with get red and sorethe 2 side buttons are NOT programable and there is no software for this mouse to do a thing with itzalman should have software for all mouse they make so you can do stuff with but they don't so sadfor the price its ok but with the bad stuff they make the mouse with to make your hand red and sore is very baduse "X-Mouse Button Control" to remap the buttons

If you just want a decent Wired Mouse for everyday use this is fine.
