I am writing this review after trying this mouse for a week. The purpose of the vertical mouse is hand comfort with a more natural grip for the hand, this Iclever vertical wireless mouse does not offer this as they have chosen to save cost and not use the same textured plastic for their mouse as in range 1 and shown 2 of the picture. The Anker brand mouse has the same textured plastic as shown in highlighted areas 3 and 4. The plastic marked 1 has no grip texture and constantly feels like the mouse is slipping out of your hand, even when it's difficult to grab and lift to move it. Note that areas 2, 3, and 4 have a matte texture, somewhat abrasive plastic material that differs from area 1. In the picture you can see and compare area 1 is more shiny or polished than anchor marked 3 because anchor uses plastic that grips and stays in your hands. Palm tree. Neither of these mice are worth buying, I also have three regular Anker mice. The only good thing about Clever is that it clicks quietly. With this mouse, you press with your thumb, which causes discomfort after a week.
