At Rs.500, you'll find 3 brands of optical mice - Samsung, Logitech and Microsoft. There are other brands, but I would not recommend going for those.
1)Logitech Offers two products:
- The
Logitech Optical Mouse USB, which can only be connected to a USB port.
- The
Logitech Value Optical Mouse, which has a PS/2 or USB interface (interchangeable)
2)Samsung offers the
Anyzen SMOP1310 Standard Optical Mouse, which has only a PS/2 connection.
3)
Microsoft Basic Optical Mouse, which has a USB or PS/2 connection
I have tried Samsung and Logitech, and a Microsoft at my cousin's home, and I will say that the
Logitech Optical Mouse USB performs better than all of the other mice listed above. Its design is also noticeably more comfortable than the normal Logitech Optical mouse (Logitech Value Optical Mouse).
The next best bet would be the Samsung. So, I repeat, if you want a good mouse, take
1st choice: Logitech Optical Mouse USB
2nd choice: Samsung Anyzen SMOP1310/Microsoft Basic Optical
Now you decide which one is for you. All of the mice mentioned above are available in black colour for about 500 rupees.
