Tried 'em, hated 'em. If placed over the existing glides there's still too much resistance. If placed horizontally the mouse rocks too much. Tried whittling down the original glides so there's less surface contact but that didn't help either, so I've chucked in in the bin.Have ordered some gaming glides to see if that improves the movement
Re Apple mice/keyboards generally... the Mighty Mouse was lovely for about a month, but the design was tragically flawed in its uncleanability. Obviously there was the joke hockey puck design too. But I've never had an issue with Apple's keyboards. Have just replaced a dead wired current model keyboard with the Bluetooth version and both are lovely (although I'd prefer a Bluetooth extended keyboard). The previous white keys / clear casing keyboard was fine, if a bit prone to getting filthy. The only one I remember that completely sucked was the AppleDesign Keyboard, which was far too light.
