Just recently purchased this mouse, I had the Logitech MX510 for several years. Does anyone that has the G5 have a problem with the back and forward buttons ? You have to push them very hard to get them to respond, just wondering if this is common. If it is I might just return this and get a different one, I like the G7 but I don't want to mess with battery packs. I really like my MX510, I just need a new mouse that the buttons were not all wore out. Does anyone have any suggestions on a good mouse ? I'd like to stick to the Logitech brand and the same style.
