I would like to share my experience with the new mouse logitech M100r. I had bought this for 480 rs from chenoy trade center near patny. This is the best mouse so far in my ten years computer career, It works very smoothly compare to many mouses which I had used like zebronics, iball etc. I wonder to see it working even on any surface I can work with it on my flat bed with no any support for it, This is very strong in design as it appears.
I suggest every one who wants to buy a good mouse at affordable price as this is the top among the best mouses. Also wireless is available in this same model but it is around 650 rs.
