Summary: After a year of use, the left click button seems to have broken. It often registers double-clicks when I click it once. Also, when I hold it down (to charge a weapon/spell in games for instance) it usually releases the click even though my finger is still done.
Summary: If you use palm grip, this mouse is just about perfect. As a claw grip user myself, I was able to adjust. I may be switching to a Corsair mouse if this issue persists.
Pros: This is a big improvement over the G500. The surface material feels nicer, and the buttons feel like they give better feedback. The internal components are *supposed* to have a better build quality than the G500.
Cons: I'm not sure how prevalent the issue is with this build version, but the G500 had enough reported problems that I'm giving up on this one. After some months of use, the mouse has started to, on rare occasions, double-click. Better build-quality was one of Logitech's selling points for this mouse....
Summary: Will return, won't buy it again nor would I recommend to anyone.
Pros: Comfortable to use, wight adjustments, nicely packeged.
Cons: Lasted less then a day. Next day after purchase speed button stopped responding, right click started to work like left click, updated all drivers, tried different settings, plugged in different USB ports, nothing helped. Mouse also feels kinda cheap for its price ($69.99)
Summary: I rarely write reviews. However, this mouse overall is pretty good for the average gamer. If you're looking for precise aiming, and "gliding" this mouse is not for you. Also, not really a pro or con for the product itself, but to me it was actually too heavy even without the weights.
Pros: The mouse overall feels great, and the amount of buttons are perfect for almost every game.
Cons: I am top end gamer, and this mouse while able to have very high DPI, is very inaccurate in testing. Every time I would try to move the mouse it always felt like something was pushing against my movement. Other mice from other manufacturers will "glide" across the surfaces, but this one always fel...
Summary: Using the software I was able to set the left click to another button which works, but is very uncomfortable to use as I it requires one to learn how to use a mouse differently.
Pros: When it worked it was exactly what I needed. A mouse with extra buttons for some of the games that I play.
Cons: Today the left click began working as the right click. After uninstalling and attempting several fixes I decided to plug in an old mouse. The old mouse works fine which tells me that this mouse has already failed within a month of ownership.
Summary: I have always been a fan of Logitech mice and have bought them throughout my whole life for gaming and personal use. To say I was disappointed in this product wouldn't be fair to the actual amount of frustration it has cost me this past year.
Summary: This mouse is one of the bigger ones, and is constructed a bit oddly. Because of the way it naturally fits my hand, my finger rests only about 3/4 of the way up both the L/R buttons.
Pros: Responsive and the software is easy to use and unobtrusive. Can easily fit big hands. I enjoyed everything about the mouse until It broke on me.
Cons: Same problem as everyone else. After about 8 months the Right button started double clicking, about a month after that same thing with the left button. It is all but useless to me now. I would have given this mouse another Star if I didn't then read the other reviews and realize this is a fundame...
Summary: It gave good service for 23 months. Then the left button started doing double-clicks, like others who have reviewed here. I really liked the feel of this mouse. I like them heavy, so I maxed out on the weights, and over a short time realized that using the programmable buttons held no benefit to me.
Summary: I purchased this Logitech G500 mouse after my Logitech G400's left-click wore out. Suffice to say, I was disappointed, but there is some good about this mouse. For example, the shape is very similar to the G400's, but slightly improved. The buttons are longer and the grips on the sides are better.
Summary: I bought this mouse about 18 months ago. It is for my home computer, so I have only been using it some evenings and weekends. Over the past 2 months the mouse has become almost unusable due to the left button either registering a double click when I only clicked once, or not registering a press at...
