Expectations met - perfectly happy

Processing and handling very well. No plastic odor. Price-performance grade 1 || got used very quickly to the mouse, the transition period lasted no week (daily. 3-4 hrs. PC work). My wife hands are medium in size (8.5 cm palm width at the outer edge of the metacarpophalangeal joints of the index to small. Finger measured). The size of the mouse fits this perfectly, it is also ideal for larger hands (tested by a friend with 10cm palm width and found to be excellent). || The driver for mouse is not present, but is replenished on request, an indication to this is on the bill. Had requested him via e-mail, reply and Link came on the same day. || CONCLUSION: Note 1 for product quality, use, price and service.
