Granted, on glass it works. But I have a few tables (a garden table, a desk), to which it moves more than millimeter by millimeter. That is totally annoying! Also an A4 sheet as Mousepad helps here * not *. If, then it must be thicker paper * * stack, approximately 500 sheets of copy paper. A multiple folded towel helps as Mousepad. Probably one could also lie a glass plate as a mousepad, but I really wanted a mouse that works on virtually all * * surfaces, and not such a throwback. A thin mouse pad on your desk does not help the way! :-(
Conclusion: where the old mouse worked fine, the Logitech Darkfield mouse fails completely their service. I would not buy me again - or if then more than a combination between Darkfield and the conventional technology, if there is such a thing once.
I wonder where all the good reviews come. Either the people have all the other tables than me, or something wrong with my mouse. But what could it be, if it works on copy paper or on fabric ...?
