When i ordered the M525, I was needing to replace my M305 because I had broken the nano receiver and it was no longer functioning properly. I really miss my M305 because it worked beautifully for years. So when i went to replace it, I immediately went back to the Logitech brand because I was so satisfied with my M305, which sadly would still work if I just had a radio receiver that would communicate with it. However, the moment the M525 came, I found the buttons to be very squishy and less quality than my M305. Within just a few short weeks the left click became very annoying and difficult to use as it would not respond even after many clicks. I finally took the mouse apart in order to see if there was a gum present or something inhibiting it from working and i only found more defects and cheapness to the quality of the mouse. After switching the primary keys on my computer in order to make the primary click be the right one, I have continued to use the M525 up until this review. I can no longer justify the use of the mouse as it is just too inconvenient and inconsistent in function. I have bought a new mouse today, but a Logitech, which I have respected as a company and enjoyed their products for years, was not the purchase I made. I went onto a new brand as Logitech no longer seems to be making quality mice.
