Logitech b100 is from Logitech company. And I am using this from a long time. I’ve used mouse which are costlier than this but the scroll breaks and eventually the wire gets ruptured . But not this one. It’s Stable and it gives me value for money. The mouse feels sturdy in hands and the laser with Optical tracking of 800 dpi is pretty good as it works perfectly on smooth/shiny surface. Over all fast working mouse smooth scroll and light click work mouse. Working in my lappy as weel as in PC. Fully satisfied, people can blindly go for this mouse, can use it for both computers and laptops.
