I've used my Thermopen for a long time, maybe a year or more, with no issues at all. Pretty hard use, too. I've kept it dry but it's been dropped a couple times and carried daily. Still dead on (checked in an ice bath) and reads fast.
I will, however, have to pick up the new model. It's faster, more accurate, waterproof- and
new! I can't resist "new and improved!"
