Anyway, I gave away my Imperator 3.5G because of the z-axis issue and the jittering while clicking issue.

Am wondering if these are fixed in the 4G version, since I really love te shape.

Currently using DA 3.5G, but it has high lift-off, and I fixed it by putting a plastic light filter between the LED and the prism, works wonder, and I can finally give that mouse 10/10, but I still wish for the Imperator shape… >”<

Firstable, you need to turn your mouse over and look at the laser censor of the Imperator which is called Philip Twin censor Eye (stupid censor causes so many troubles). Do you see around the censor and the eye the censor? Is there dust around it or not?

Next, you need to use a blunt small stick and use a small amount of cotton wool. Have you figured out what do I mean? Yes, you need to use cotton wool and the stick to clean the censor eye. Remember you do not need to use water so a dry cotton wool is good enough. Then you need to clean the laser eye carefully and gently, do not push too much power on it or you will break or damage it. Gentle as a woman takes care of her child.

After cleaning it in 1-2 minutes, you can use the mouse normally. This solution could tackle the mouse axis lock and Z-axis over 50%-70%.

I tried it with my 4HD. At first, I though the mousepad caused trouble but not, and then I looked at the laser censor and I can see the dust inside and around it. So I tried to use above solution and It worked. Thanks god for blessing me!

I used other mousepad such as my old Razer Mantis Control and white paper. The mouse track well on these materials but not on the 4HD. However, I tried to move the mouse on the mousepad in 3-4 minutes and the mouse worked on 4HD.

But it was not over yet. The feeling on the 4HD was very good and smooth until I recognized something wrong happened. The Imperator did not tracked well on this mousepad, it was lag and unprecise and sometimes it stopped working on this mousepad.

Enough is enough. I do not want to stick with Razer company anymore. Imperator is enough for me to say goodbye to Razer forever. This mouse sucks, Razer sucks.

I will try Logitech G500 or SteelSeries Sensei next time but not Razer.

@Cipic, black pads shouldn’t be a big problem, your mouse might be defective.

The Z-axis is not really a big problem for me because I use high sensitive and DPI in work and games too. I really don’t need to lift the mouse of the mousepad most of the time.

And about the dynamic dpi scaling problem. I updated the newest firmware 1.16 few weeks ago and the problem disappeared. I do not know if it will happen in the future or not but it is okay now.

The newest firmware could tackle the turn on and turn off of the mouse randomly too.

But you need to uninstall the driver after you update the newest firmware because the driver is main thing that causes so many problems of this mouse.

In addition, remember to use a non-colorful mousepad. I am using my Imperator with a white paper now.

Hopefully Razer company will improve the quality of their products in the near future. The Mamba, Naga or even the Imperator 2012 version still have so many errors. What happened to the Razer technology? They were so good such as Razer Copperhead and Diamond Back. But now it’s quality is dropping.
