Logitech M705 Owners: "Mushy" left clicks

[taisingera]

I just bought a M705 from Walmart, and I might return it before the 15 days. The tracking doesn't even seem to bother me with the off centered laser. However, I find the left mouse button to be very "mushy" feeling, and too soft when clicked. Also, when you tap on the right mouse button, the button literally shakes a bit. I am coming from a Logitech G5 but even my M305 cheap optical mouse seems to have sturdier button clicking than this thing. Anybody else with this mouse find this to be an issue?
