They're my least favorite thing about the design of the G502. But unless you really feel like you need an extra two buttons next to your index fingers, these buttons feel tacked-on and more likely to cause misclicks than anything. There are plenty of solutions to this problem: rebind the button, disable its binding altogether, or simply spend long enough with the mouse to hone in my muscle memory to avoid misclicks. Many times over the past week I've sent my cursor flying across the screen by accidentally pressing DPI+ instead of left-clicking. They're simply too easy to press, and by default serve as a DPI switcher. I sometimes feel like my finger is slipping off the edge of the right-click button, and because the left-click is relatively narrow compared to most other mice, I find myself often accidentally clicking one of the two smaller buttons Logitech added to the left corner of the mouse. There's a strange, slightly offputting asymmetry to the left-click button being concave, scooping inward to hold your finger, while the right-click button is convex and slopes off to the right. With five years of perspective, this part of the G502 feels overdesigned. Unless you really feel like you need an extra two buttons next to your index fingers, these buttons feel tacked-on

You can also click the wheel left and right for more button inputs, a rare feature these days that I love having as an option. A button below that wheel lets you switch between smooth scrolling, great for skipping through a 100 page document in a flash, and notched scrolling, more ideal for swapping weapons in an FPS. The G502 does feel solid: a good bit of that weight comes from the metal scroll wheel, which has such a wonderfully smooth and satisfying scroll feel under your finger it'll be hard to go back to any mouse that doesn't have it. It weighs 121 grams, with an additional 18 grams addable with some small metal weights that fit into the bottom of the chassis. It's still the best choice for a large, heavy gaming mouse around. But it remains a great gaming mouse with features few competitors offer, and with a new sensor that will keep the G502 competitive with anything released in the next five years. The Logitech G502 is bigger and heavier than I'd recommend to most gamers, and I think Logitech and other mouse companies have surpassed its design in the years since it first released.
