"Tiz3r" on the QL forums mentioned he had this mouse and liked it. I had never heard of it before.

Basic Information:

800 cpi Optical

3000 fps (vs. 9000 on the wmo)

LOD comparable to the wmo

20 inches/sec malfunction speed (MS states the same for the wmo, hard to know how truthful it is).

92.8 grams with cord. To give you an idea MS lists the wmo as weighing 125 grams with cord, without cord it weights about 77 grams, a 48 gram cord. If this mouse has a 48g cord it would weigh 44.8 grams.

It appears to have a better scroll wheel than the wmo.

Sensor info:

Per the photos, it appears to be a PAW3502DLZ-M2 .

The closest data sheet on that I could find is here:

http://pdf1.alldatasheet.com/datasheet-pdf/vi...asheet.pdf

Which refers to a PAW3502DL 800 CPI. I couldn't find any reference to a DLZ-M2 anywhere.
