Pros: Accurate, easy non-harrassing
Cons: none that i can think of
I baby-sit for a lot of my relatives, and I recently had to use this on my cousin Jerry, who is currently teething. I think anyone with a child knows how difficult it is when the baby is crying and red-faced and unhappy, and seems to be running a fever.
Anyway, it's very hard to take the temperature with the old class thermometers, in fact, impossible for me, I never could get them to work on children, as to hold them down seems cruel, and if you let them move, in the many minutes it takes to get the right temperature, the baby is liable to crawl away, or simply work it loose.
This baby thermometer is a lot nicer. I did use it rectally the first time, because his mother wanted to make sure I could do that, so she made me check him that way while she was still there, which was fine. What was nice is that I could sing to him and get his attention away from the very distracting thing poking out of his behind, so I got an accurate read. Basically, it beeps in about 45 seconds, so you don't even have to mind your watch. I thought that rather clever.
Also, what's really nice is that you get an even easier reading by putting it under the babies arm, which you can do once he/she is sleeping. The little beep didn't wake him up, and I also had peace of mind, as I really didn't feel like paging his parents, who were trying to have a peaceful dinner, unless he was seriously sick. And thank goodness he wasn't.
So, I highly recommend this thermometer, because of it's ease of use, the versatility of it, and the low price, which was about 8 dollars.
Thanks for reading!
