yea . . soft pad may cause this issue . . and well my problem is the mamba sensor doesnt reactivate itself after u reposition your hand due to limited wrist movement . . normally the mouse sensor will cut-off after u lift-off the mouse 1mm above the surface . . when the mamba is placed on the surface again . . the sensor doesnt reactivate for about 1 or 2 sec and thus any movement will not be detected by the mouse . . this happen on my razer exactmat and my mouse is with the latest firmware . . teflon ring also black one . . funny thing is this doesnt happen on plain wood table surface . . i'm not the only one facing this . . check out these two links:

checked with razer and they do not have an answer for it . . instead they ask me to RMA it.

Juz RMA it two days ago since Razer asked me to . .

As you can see from the two links, one of them using destructor also got issue as destructor is pliable . .

Done some research, and they recommend razer pro pad with mamba as it is a hard pad and white in colour which is better to laser mouse . . compare to my razer exactmat

Did they specify which brand of mouse? Any mouse will do? Or Razer mouse only?
