I bought the black X802382 one a half year ago. I liked it and pretty much owned at playing CS 1.6.

But, 2 months ago, I don't know why, the sensor felt weird. I supposed it was caused by me swiping it too fast several times so that a certain part in it loosened? I did that to test the mouse maximum speed using a program.

Was it possible?

So, a month ago I bought the white one, the same X802382, but got it from a different seller. This one's a WMO 1.1A, while the other one's just WMO.

This one has a transparent base and more solid build. The clicks, the scroll, the cutting edge of the shell feel more expensive.

One thing that intrigues me is that the sensor feels a little bit different. But, this super slight difference can make a big impact in a game such as CS 1.6, where u have to control gun recoils. A very slight faulty movement will ruin the recoil control.

I mastered the black one in only a few hours. But, it's already been a month since I've had the white one.

Both have no mouse prediction, tested in paint.

What r the chances that I've got a defective WMO 1.1a?

Don't question my skill, I used to own with the black one while using the white one I look like a complete idiot at controlling recoils.

I blame either the defective mouse, the mousefeet, or my too dirty mousepad.
