Review on Logitech M170 Wireless Mouse - 2.4 GHz, USB Mini Receiver, Optical Tracking, 12-Month Battery Life - Blue by Jason Sisawang

The flimsy construction and scroll wheel increments are so frustrating that they cannot be used. Two main disadvantages. First, both mouse buttons are very weak. Forget touching the mouse or touching with your hand. The smaller the touch, the more it snags, especially the right one. Secondly, the scroll wheel is not analog, the movement is smooth. It's graduated in clicks, clicks that move the arrow a long distance, making scrolling nearly impossible. The thing works as it was intended, it was just very poorly designed. If you buy it, expect to give it to someone you don't like.
