Pros: good idea

Cons: poor implementation Since it is a surface device, you can't rest your fingers on it or it can't tell if you're clicking left or right. I had to hold the mouse by the edges to move it, my click fingers hovering above it. So it's very uncomfortable to use. Often, when I right click the mouse does a left click even when my index finger isn't on the mouse (or slightly touches the mouse). The only consistent way I could get a right click was to click the right side hard. Sometimes, my fingers will barely touch the surface as I'm moving the mouse no matter how careful I am. This scrolls what I'm trying to work on. I could disable the scroll but then what's the point of having the surface in the first place? There are currently no sensitivity settings in the driver so no way to tweak it. Even if some if the issues are because I got a defective mouse, it looks like a bad design to me. After 2 days of trying to make this mouse work, I returned it.
