If that's the $9 thermometer at Home Depot, I like it a lot. It's taper tipped so it's fast. But since it's $9, don't expect longevity. I replace them no less than once a year
I liked mine a lot but it stopped working after 3-4 months
*edit*
thanks for bringing this up, actually. It just made me search about replacing the battery.... turns out it is replaceable, I thought it was not.
