I 'thought' they were dependable
Had one crap out on me this weekend in my contest. I think somehow it got moisture in the thermocouple, although the fact we had 5" of rain and I did all I could to keep the EZ Up from blowing away in the 40 mile an hour winds at 2am MIGHT have something to do with it.
I'm going to test it this week.
Other than that, I'll buy another one, even if it's pricey, because of the fast read.
I use it for competition, but for home use, you could get away with a good regular one if the price is scaring you off.
