That's a very good point to make!!@Wickedchicken6 and @venymae
jut be careful with the thermometers that the temp is on the background and not on the actual thermo, the backing can move
and that can be the reason the temp is so off
The basic hardware ones are glued and I checked them every time I calibrate to ensure they're still solid. I've only got two that are no longer trustworthy and that may be because I dropped one hardware therm and broke the bulb from the holder.
The other was an aquarium therm of which I dropped, and then proceeded to step on and crush in a most spectacularly, unbalanced move.
