Summary: this is a nice mouse. it shows to get a fairly decent mouse, as this seems to speed up my mouse speed on my computer. my old mouse was just getting slower and slower on responding. this new one improves my speed and responding, vastly.
Summary: well worth the money. a bit more play in this - took a couple days to be comfortable with it. appreciate the abidexterity as i prefer to use my left but also type with left more and use right handed clicks when also typing. still like the olde plug & play.
Summary: My H/P desktop was getting slower & slower. Another reviewer mentioned a dying mouse. I was looking for a desktop mouse. The Logitech B100 is a desk/note sized mouse. I once had a true nb mouse (wireless) -- WAY too small. Keep this in mind - the B100 IS NOT a true desktop sized unit, but for the cost ($10) it's worth it. Considered getting a cheaper mouse, but they were all bashed - quality/value-wise.
