Corepad CS28090 Skatez Mouse Feet for Logitech V320, V450

Also fits the Logitech M525. I've got two M525 mice on the go at the moment, one with the original feet, and one with the PTFE Skatez feet, and the difference is very noticeable, particularly the reduction in stiction. Out of curiosity I did a little stiction experiment with a bit of thin elastic and a ruler, and it takes three times the force to overcome stiction with the original feet compared to the Skatez. If I'm using a mouse all day then all that extra drag adds up to an aching arm.The profile is accurate and fits into the moulding nicely, the PTFE is tough (my last set of Skatez outlived my mouse), and most importantly the mating surface is flat and sticks well. It's easy to stamp out a shape out of a bit of PTFE sheet - which is essentially what these and similar mouse feet are - but finding an adhesive that sticks to PTFE is tricky, and these stick very nicely indeed.I should knock off a star for not listing the Logitech M525 in the model list and making me gamble on buying feet that might not fit, but I'm so pleased with the transformation in my mouse that I'll let that one slide.
