The first is always a chance with any switch. The second is usually in the hands of the device manufacturer. Given enough use and time, the last two are inevitable and universal.
Firmware updates can help refine the debounce time. If you have a switch that is only slightly off, you might just get lucky there.
Otherwise, as I've said a thousand times and will say a thousand more, open up your mouse and clean the microswitches with electrical contact cleaner, and bend the springs back into shape if needed, or if they are particularly far gone you can remove the whole switch and solder on a new one. These are fairly simple and dirt cheap fixes / maintenance tasks that I feel everyone should become accustomed to unless they just want to buy new devices constantly.
Of course, as always, RMA before doing any repairs yourself, as long as it is still in warranty.
