If you travel a lot with your laptop, then this elegant and impeccable quality mouse is right Instrument for its operation. It is small and takes in the notebook bag barely space. The connection connecting cable can take off. After a quick jerk the cord snaps at the desired length. Likewise GE suffices a quick jerk to carry the cable back to its original position. The mouse has a high resolution which is why I have asked personally a little slower for me. For my hands it is also a bit too small, but as I said still very convenient. It does not require batteries, so is always switched on ready for use. There are mouse in different colors, it is very inexpensive and that's why I can in good conscience Recommend.
