I recently purchased this "Logitech B100" USB mouse from online shopping site snapdeal on their "Unboxing Sale Day".The selling price of this mouse was Rs.279, but I got it at Rs.179.Packaging and delivery were decent by snapdeal and now I have been using this mouse for last one week, I did not found any problem.It is working perfectly and very smoothly.Pretty much works as a plug & play.Sensitivity is also good and very soft.The cable length of this mouse is sufficiently long and quality of USB connector is also very decent.The interesting thing about this mouse is, we get 3 years warranty by Logitech and I think at this price range you will not get such long warranty period from any other brands.My old Logitech mouse worked for 3 years and I hope this new one will also last long.So, I will definitely recommend this USB mouse for every desktop and laptop users because the brand is reliable and the price is also affordable
