Pros: They work!
Cons: Only works in a few models, only 6 in a package, expensive.
When we purchased our Vicks Waterless Vaporizer, five pads were included in the package. Since they only last, at the most, eight hours, you can go through them very quickly.
The Vicks Soothing Menthol Scent Pads come in a box of six, which can often be a pain in the backside to find. The box is small and easy to overlook, especially when they're on the top shelf at Wal-Mart, like ours are. Each scent pad is individually wrapped, which helps them last in case you don't use the whole box. The expiration date on the bottom of the box tells you when they need thrown away if you have leftovers.
The Vicks Soothing Menthol Scent Pads are only 1 1/2" long, just under an inch wide and about as thick as a nickel. We use them in our Vicks Waterless Vaporizer, but they're also good in a few other models.

Be careful when placing the Vicks Soothing Menthol Scent Pads into their spot on your vaporizer because it takes a lot of soap to wash the menthol from your fingers. I usually tear open the plastic package that it comes in and drop it into the bay of the vaporizer, so I don't have to touch it until I remove it in the morning. Often, however, I'll just turn the whole unit over and drop the Vicks Soothing Menthol Scent Pads into the trash, after it has been unplugged for a bit, and cooled.
How does it work? The vaporizer heats up under the scent pad. As it heats up, the Vicks medicine that is in the pad is released into the air, filling the room with the menthol vapors that help clear your stuffy head. As it dries out, it becomes less effective, which is why they don't quite last the full 8 hours the box says they can. Ours last 4-6 hours, as I usually use the middle setting. They really start to stink when they dry out, reminding me of burning rubber. I'm not sure why the smell is so bad once the medicine has been used up, but they do.
The Vicks Soothing Menthol Scent Pads are very small and are a choking hazzard if your child puts things in their mouths. Make sure to keep them up and out of reach. If your child should put one in their mouth, contact Poison Control ASAP!
While the Vicks Soothing Menthol Scent Pads work well, I wish they were not only a little bit cheaper, but that they came in a larger package. I've only seen them in a box of 6.
