Pros: Moves very well. Feels great to use and is aesthetically pleasing.

Cons: The middle mouse button is a bit too hard to press in contrast to the left and right that are perfect imo. I use this button almost constantly since I work in Blender for 3d modeling so it's a bit annoying. Though I'm sure I'll get used to it in time.

Overall Review: All in all, a very nice mouse.

Pros: Holds a good amount of space.

Cons: Seems to be unstable and malfunctions quickly. Used this for work and when it died it set me back a month's worth of work.

Overall Review: Would recommend getting a more well-known and trusted hard drive.
