I bought a set of G305 feet last week directly from Corepad. I'm sad to report Corepads are still pretty ****.
1) For some reason the backmost foot is not rounded whatsoever. It's 100% flat and I see it leaving streaks on my mousepad, so I took it off.
2) Even with this piece taken off, the feet are not rounded properly. They are rounded to a certain point, but past that thickness there's a sheer edge. I can feel them scraping against my pad as soon as I apply any pressure to the mouse.
I think this company is managed incompetently or something. It cannot be this difficult to round mouse feet. I'll just buy Tiger Arcs in the future.
