Logitech M185 is on of the best optical mouse available in market.If you want to online then it cost less then market price. I bought it from Snapdeal in rs.609 only. It is cheaper in cost as compare with other branded optical mouse like Dell and Hp. I am using this since last 6 months without any problem. It’s battery backup is so nice still I am using its own battery come with mouse.
Its range is higher around 6-8 mtr and comfortably fit into your hand. It is worth of money. I recommend it to all if you want to buy new Optical mouse.
