My +:
, looks good :-P
, the micro receiver is to pack an directly into the mouse. This switches your mouse, very convenient!
, the 2.4GHz allow free movement, a use on all surfaces (pillow, table, paper, clothes ... I use no mouse pad
, Switch under the mouse to disable
, Battery (2 AA 1.5V LR6 times) until now (after 11 months, ~ 10 hours / day) still alive!
The -:
, Well ... I white not, maybe the price, but ~ 50 is acceptable, I think.
To know about, price / performance very high, am totally satisfied (until now :-)).
