Why it's labeled "The Lord of the Rings" I don't know. Not sure what that has to do with anything - if you know, feel free to fill me in. Possibly, one computer mouse to rule them all?
The major misconception about this optical finger mouse, appears to be how the mouse actually functions. It has to make direct surface contact to make useful pointer movements, just like a normal USB mouse. The difference is just in the delivery - it is small and strapped to your finger instead of resting under your palm.
The package claims 1600dpi but the product page only claimed 1200dpi - not sure if it really makes a difference either way, since it didn't work on several surfaces I tried ... places that would have made its design functional (i.e. the laptop palm rest area).
It does not list Windows 7 specifically in the compatibility list, but it loaded quickly and without any problems on my 64 bit system.
It seems to be constructed of sturdy plastic, but the buttons are a little light and very sensitive - I had some trouble with accidental presses while testing. The scroll button is sturdy and fairly fluidly turns, but does not offer the clicking function, which I use all the time.
There is no protective covering for the LED nor the sensor, leaving them vulnerable to dirt, dust, hair, lint, etc, clogging, or just getting directly damaged.
There is a big open gap in front of the scroll wheel which seems like it might get clogged by similar contaminants over long periods of time.
Overall, I wouldn't recommend the mouse as it didn't work where I wanted/needed it to, and it didn't offer functionality that I use repeatedly. If you use it where you don't have stable surfaces, like in bed or on the couch, you might find it helpful though.
