Summary: I thought I was crazy for a long time. I decided to pull out my old G5 which still works, but it malfunctions at high speeds. Being careful not to zip the mouse across the desk, I was amazed to find I am not crazy. The precision and control of my G5 reassured me that the G500 is total crud.
Pros: It's about the same shape and size as many other Logitech mice.
Cons: This mouse is horrible. At first I thought it was just that the sensor is up by my fingertips with this mouse instead of near the center of my palm like with the G5. After fiddling with everything for months, it is obvious that this mouse's sensor is seriously messed up.
Summary: This used to be my favorite mouse, I have owned 2 and the first one never gave me problems, but when I gave it to a friend he said it went out after a month.
Pros: Great feel and weight, perfect amount of buttons on the side for a FPS player, and love the DPI settings.
Cons: The mouse went out after a year of use, mouse keeps just shutting off after about a minute of use. I tried fixes on line, like updating audio drivers, but it didn't work. I put in another mouse and it works just fine. Hopefully I can get a RMA from logitech, but not expecting it.
Summary: I considered giving this one star because most mice I've had before this lasted at least 5 years. However I could not ignore the fact that its got good features and those features work well. If you're willing to buy a new mouse every two years then this might be the mouse for you.
Pros: The advertised features of this mouse are what drew me to it and have worked flawlessly for around 2 years.
Cons: Two and a half years later the critical left and right mouse buttons emit double clicks instead of single clicks. A simple search shows that this is an extremely common problem with this model. There are two causes: 1) poor quality mechanical parts in the button switch. 2) poor electrical design ...
Pros: Great feel. Love the on the fly DPI change and programability.
Cons: If it wasn't wired I would have probably thrown it through the window. Took me too long to realize it was double clicking on it's own, making spreadsheet work next to impossible. A quick web search shows this is a VERY COMMON problem. It's a shame, otherwise still a great tool.
Pros: *weight adjustment *fits well on your hand *red light ;)
Cons: had it for 1 year i think, i play fps a lot (ghost recon phantom) so i use the left click everyday in intense battle. now the left click isn't functioning well when I am pressing hard the left click its not responding anymore. its annoying that i have to think about my mouse when i am shooting so...
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: Would specifically avoid this model in the future due to defects.
Pros: Nice mouse, high DPI, can configure speed on the button, has mousewheel "clutch"
Cons: Nav buttons are annoying, sometimes accidentally hit them. Left mouse button faulty switch is an extremely common problem. After about 2 years, mine started double clicking randomly. Working with Logitech to hopefully get a replacement but the outlook from what I've seen on forums looks gloomy. P...
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)
