They are just some sort of desiccant with the bag gimmick. If you have some desiccant packets saved that ship with hard drives, DVD drives, video cards etc, you can use them. Amazon has this and this which are cheaper than the bag.

Compared to replacement costs of MP3 players and cell phones or bike light bench charges and even shipping on warranty items, the $10 or so seems well worth a try.

MacGyver would put the PBSF in a baggie with some (raw) rice for a day or so and should work better than a hairdryer.
