- The mouse is constructed out of high-quality materials and has a unique top scroll that can be challenging to get used to in the long run. In the span of two days, I was completely oblivious to the widespread scrolling issue.
- Having used the original mouse in the line, the mx performance, and now having the mx 2 in my hands, I can tell without a doubt that this mouse sits differently in the palm of the hand than its predecessor. The grip is not very pleasant, and it has the appearance of having been designed for a smaller or narrower hand—possibly the hand of a woman. I was never able to get used to it; even a regular mouse that lacked an ergonomics sight did not cause me as much discomfort as the MX 3. I was unable to put my hand on it in a way that was both comfortable and allowed me access to all of the buttons and scrolls without shifting my arm position. Although in size it virtually equates to mx 2 or performance - a little smaller, it has lost volume where part of the palm is placed closer to the wrist and the hand remains on weight as a result of the sharp cut on the top.
