The Arc Mouse is an exquisitely designed product with a feel of high quality to its build. It's light for a wireless mouse and glides across work surfaces with minimal effort. The buttons are quiet and require very little force to press, making this a very comfortable mouse to use.
The mouse's most unique feature is its fold-away design, which also functions as its 'off switch' for storing in its magnetically-closing leather pouch. The hinge is made of steel so it's very robust. It also snaps into the 'closed' and 'opened' positions. The tiny wireless USB transceiver stows securely in place (magnetically) on the mouse's underside ensuring that it never gets lost.
The Arc Mouse has a 'Back' button on the left, which should ideally be placed closer to the middle of the side (where it could more easily be reached with the thumb), instead of at the tip where it's placed, but this is a minor point and not a flaw by any means. The top surface is made of a rubberised plastic, edged with a shiny piano-black bezel.
The Arc Mouse uses a laser to track movement and is very sensitive and precise. It's excellent in both office applications as well as in gaming.
It looks modern, it's very comfortable to use and is of a very good quality. I love it and highly recommend it to anyone is search of an excellent wireless mouse.
I've been using these for over three years now, and still love them. I've got one at the office and one at home. As a draughtsman and gamer I use the mouse wheel a lot. That said, the wheel is the one flaw on this mouse. It is pretty much guaranteed to fail after some six months of heavy use. This is very disappointing, as the rest of the mouse is perfect. Still, even with this one flaw, I keep replacing them with new ones as I've yet to find a better alternative.
