I have used Logitech mice and keyboard, wired and wireless, multiple series for years. I have been using the same mouse on this computer for 2 years and no problems, this keyboard for 2 years no problem. Pretty intensive usage and they still hold up. The last time one broke on us was 2 years ago after about 3 years of usage. Are there any better brands? I have used K120's K360's M100's, M325's M510's and M560's all on different PC's. They are really reliable. Again, any better price to durability?
