I run a home daycare and have tried all of the following:
Ear thermometer - too hard as you HAVE to know you are hitting the right spot - good luck with sick kids, especially with ear infections
Temporal thermometer - also too hard to keep "flat" against the forehead - I kept getting a different reading every time I ran it across my own forehead therefore I don't trust it
Vicks ComfortFlex Digital Thermometer - LOVE IT - fast, consistent, more comfortable for babies, large digital readout, Fever InSight Feature (flashes red if there is a fever) and also will give you the last temp. reading when you first turn it on (comes in handy if you're memory isn't so perfect anymore like mine). Best part: INEXPENSIVE and I use the thermometer covers with mine.
I spent a lot of money on the ear and temporal thermometers. I think I used them once or twice and was so frustrated with them. I would end up always reverting back to a basic thermmomter. I highly recommend the Vicks ComfortFlex.
