Query: Only some optical mouses work on this

My microsoft optical comfort mouse 3000 does not track at all on this, while I thought it could track on just about any surface. However, I also have a logitech mouse for my laptop and it seems to work fine. I guess if you buy this, you will have to cross your fingers and hope that the mouse pad will work. Apart from this, I like the texture and the materials, and the pad is comfortable. However, the two sides enclosing the gel are glued and not stitched together, so I'm not sure how long this will last.
