Summary: I was given one of these for Christmas, because I was always complaining about the fussiness of my previous laptop mouse with regard to the colour of the surface being used that the mouse wouldn't work on. It really is fantastic! It will work properly on any surface at all, be it plain, coloured, patterned, or even glass.
Excerpt: I ordered this mouse and after the shipment arrived I was surprised to find that it uses infra red OR (invisible optic) tracking system instead of usual red/blue light tracking system. I removed the alkaline battery provided and inserted the rechargeable 2100 mah battery. Compared to other wireless logitech mouse which uses red light tracking and lasts about 25 days on single charge... this mouse is working fine on the same battery for about 90 days and counting.
Pros: Accurate Tracking, Comfortable Design, Fast Response, Glides Smoothly
Summary: Absolutely no problems..also no red glare from the laser light at the bottom..good cos i always found it annoying... Just plug n play and performs like a work horse.. Have seen my friends using this model for well over 5 years.. Worth every penny.
Summary: Look wise it's good. Have good reception range. Comes with pre-installed duracell battery. Got quickly installed on Win7 Pro. Flipkart got it delivered much before the expected date. Great job!! Overall good product and nice service from flipkart and seller. ThumbsUp !!
Summary: The mouse is small and comfortable to hold. It is a unifying receiver device, which means I got to use it with my previous receiver and not take extra USB port of it's own. The battery and receiver compartment are below the mouse. The overall look and feel is quite sturdy and well built. The only thing bothering me is the battery window being a little lose, which makes a clicking noise when I lift and put the mouse back on surface. Otherwise, a good product.
