2 out of 5 eggsToo small. Hurts my hand.

Pros: Cheap.
Looks cool.
Blue LED.
Good buttons.
Tracks well.

Cons: I've started having carpal tunnel symptoms. My pinky finger feels numb and aches. These symptoms only started after using this mouse. I guess it's just too small. My hands aren't even large. I would sometimes hit the side buttons by accident. Also the LED is always on and doesn't change colors to give a visible indication of when you're switching between DPI modes like my old mouse did.

Other Thoughts: I wouldn't recommend this unless you have very tiny hands. I wouldn't purchase this particular mouse again but the quality of it was fine.

3 out of 5 eggsWon't recommend for Gaming

Pros: Good mouse for average PC user.

Cons: I won't call it a gaming mouse as such. It's too light weight to be called one. The DP rate is too low. I find it hard to track an enemy during FPS Multiplayer gaming.

Other Thoughts: I won't recommend it specifically for gaming. Good for everything else.

4 out of 5 eggsGreat little mouse

Pros: - It's kept well over the time point of 2 years (only 1 issue)
- Has lasted many falls and survived
- Works on bumpy desk without mousepad
- Middle Clicking (pressing down scroll wheel) works reliably
- Additional Buttons work easily
- Performance has kept up over the 2 years

Cons: - It is in fact, as a previous review has said, a bit small - but not too majorly so, and it only takes a little bit to get used to.
- The looks do get worn down a bit over the years, but somewhat expected

5 out of 5 eggsGood Mouse!

Pros: Was looking for a gaming mouse with extra buttons for my games this mouse delivers more than expected very responsive and has not failed me yet and for the price i have no regrets.

Cons: Im not going to knock an egg off but the DPI switch button on the mouse doesn't do anything when i press it but that doesn't get in the way of my gaming.

1 out of 5 eggsNot Sure

Pros: Ergonomically comfortable.

Cons: Stopped working after three days.

Other Thoughts: Haven't heard back from Zalman customer support -- 1year warranty should cover defective mouse -- we'll see.

5 out of 5 eggsM400 Review -- Great Mid-Level Gaming Mouse

Pros: I purchased this ZM-M400 gaming mouse to upgrade from a retractable mouse. This mouse is great for gaming and has an even better price tag.


1. It has a 4 foot USB cable to reach around a computer comfortably.

2. Gold-plated USB connector for increased transfer speeds.

3. 6 buttons that can be customized to operate to your preferred commands.

4. 3 different dpi levels. Which if you are a gamer becomes very helpful. With just a click of a button you can go from the typical Microsoft mouse to a lightning fast and responsive Zalman gaming mouse.

I have a laptop that I game on (currently putting together my gaming desktop!) and on a 16" screen at 1600 dpi I can fly from corner to corner in 1/4 of a second. Then for typical applications one click and I have a very controllable cursor.

I have used the Zalman mouse for Team Fortress 2, Left 4 Dead 2, and Civ 5. When rapid clicking is needed the mouse has low sound/easy click buttons where nothing sticks and there is not lag. The buttons are always ready to go waiting for the next click . Precision of the mice are superb for a $20.00 mouse.

I would recommend this to any gamer of FPS or RPG games alike.

Cons: This mouse is not the mouse for MMO games. If you play anything like World of Warcraft or any game that needs about 10 buttons or if you have a large screen then this mouse is not for you.

It only has 6 buttons so it can become limited to anyone with complex command games like WOW.

The larger a monitor, the more dpi that is needed to cover the same distance on a smaller monitor. If you play computer games on a large screen monitor or TV you might wan't to find more dpi in a mouse or one with more levels. Any screen 23" or lower should be perfect with this mouse.

Other Thoughts: This mouse is great for mid gamers and those with screens about 23" and smaller. This mouse's dpi may work at larger screen sizes but it is just preference.

Most mice of this caliber are about $35 dollars so seeing this mouse for $20 it was a great grab. Zalman has innovated their line of hardware and I am impressed by the quality of a $20 dollar mouse. I don't see the need to upgrade unless I want more buttons to use at my command.
