Review on Lenovo GX30M39704 300 Mouse - Wired USB for 320 Touch-15, 320-14, 320-17, 520-22, 520-24, 520-27, 720-18, Legion Y520-15, V110-15 - Right and Left-Handed - Black by Juan Russell

So my review might be a bit more helpful. I'm a big gamer, I have about 20 keyboards and 40 mice in total. For non-gaming purposes, cheap mice are better suited. If you want to buy an expensive ergonomic mouse, buy a gaming mouse, not one of those $40 ergonomic mice. For work and light gaming, this $8 mouse is perfect for Logitech M100, B100, etc (looks better). Ready mouse with 1600 dpi (Thanks to Lenovo). The tracking is flawless and the design looks damn clean. Trust me, the cheapest no-frills wired mouse is the best discreet mouse, and that's true for most companies. I have medium sized hands and the shape is great. Even people with big hands will like the grip. I gave it a 4/5 instead of 5/5 because the left and right click buttons either seem a bit harder to press or mine got wrinkled during shipping. However, it cost $8, so I'm going to buy a few more of their cheap models and try them out. If you play LOL, this mouse will do. There are not many FPS games like COD and Overwatch. 1600 dpi is a good setting since Logitech mice are (in most cases) 800 dpi or 1000 dpi. I have a Logitech MX Master but I still use it. If you're a busy person who needs to spend most of the day in front of a monitor, then get this. Fancy ergonomic mice distract people who are easily distracted or who suffer from ADHD in a number of ways. This mouse has been around since Lenovo started making consumer computers, and there's a reason it's still around. The thing is a classic.
