Summary: The VX Revolution is probably the coolest notebook mouse on the market as of December 2006. Along with it's big brother the MX Revolution, the VX has the most sleek, striking, and thoughtful design I've ever seen in a mouse. The wireless receiver slips very neatly into the base of the mouse - much more neatly than other notebook mice I've seen.

As for basic functionality, the VX performs flawlessly with great wireless signal reception and very accurate laser tracking. I don't play games so I cannot comment on how it would perform in that environment, but for everything else it's great.

It's the advanced features that really make this mouse cool. First, you can linearly adjust the \"clickiness\" the scroll wheel using the \"microgear\" adjustment on the underside of the mouse. This is very slick - you can choose anywhere from a well-defined clicking feel to a completely smooth feel. The scroll wheel itself feels good with it's rubber coating. Horizontal scrolling, which is accomplished by pushing the scroll wheel to the left or right, can feel a little bit awkward, however.

I've found the zoom adjustment, located just to the left of the left-click, to be extremely useful. No more Ctrl+/-! The back and forward buttons, pressed with the thumb, also became useful once I trained myself to remember to use them.

One advanced feature that didn't work out for me very well, in Firefox at least, was the One Touch Search. However, you can reassign the functions of all the mouse buttons with Logitech's SetPoint software. This software is easy to install. It is necessary to run it in the background all the time (using about 14MB of RAM on my system) in order to use the advanced button functions on the mouse. I have found running the software to be undoubtedly worthwhile.

The only negative comment I have about the mouse is ergonomics. The mouse seems to have been designed intending the user to wrap their whole hand around the mouse. However, because the VX is a notebook mouse, it's compact and quite rounded, meaning that if I grip it with my whole palm on it, my whole hand is quite curved, which can become uncomfortable. In order to avoid that discomfort, I hold the mouse sort of loosely and angled a bit, making it a bit harder to access all the special the buttons than if I firmly gripped the mouse. Even so, my hand still seems more curved than with my old Logitech MouseMan, making me concerned about the risk of carpal tunnel. I suppose this is a matter of personal preference, but I recommend trying this mouse out at a store before buying. The MX Revolution may be a bit better in this regard if you don't mind a little extra heft. For this reason, I've given this mouse a 4 rather than 5 star rating.

I recommend the VX Revolution; just make sure you try before you buy.

Summary: If you survive and forgive the SetPoint software (refuses to install on Windows 2003, sends events to wrong windows, forget about scrolling in a frame in IE, horizontal scroll is a toss of a coin), the catastrophic event is awaiting you 3-4 months down the line (maybe 6 if you don't use it much).

The problem was reported on Logitech support pages, and the only \"solution\" someone (not their support) came up with was to remove the rubber grip from the scroll wheel, replace it with a putty and paint it :-) Apparently that rubber starts expanding and the casing was built to a way too tight tolerance so it starts rubbing off - kills all inertial force that makes the wheel fast.

Logitech support plays silent, company started reducing the price of the mouse, but honestly no price reduction will do if you have to buy 4 mice per year. Also mouse is very tricky to open and even trickier to close (a few small springs may jump away), so even if someone would make a replacement grip it would be pretty tough deal to replace it properly.

Bottom line - unless Logitech releases new version/model that would have user replaceable wheel (and/or wheel grip), the \"Revolution\" is dead. Extra problem is that after 3-4 months your fingers get used to the speed, so one is better off not trying in the first place.

Summary: This counts for all the Revolutions models:
The mouse wheel has a rubber ring which after a few months becomes loose. The wheel will not run freely anymore and will become useless. Logitech has a great service. They replaced my mouse for another one with the same problem.
