No issues worked great!

I've tried many different thermometers and these are my favorite! They're very easy to read and stand up well in my pitchers!

These thermometers are great!

This was super affordable and did the job great! :)

no issues with mine really, reading correctly. love that it is super easy to wipe clean with paper towel even when i use it with beeswax.
price is super great, do have minor issue with clip being so stiff/tight that i can't clip it to pitcher.

only problem with this glass thermometer and guessing all others like it too, is that the heat from double boiler steam the glass and obscure the readings so you have to pull it out and wipe it quickly to see the temp. perhaps a top reading thermometer would be best in the end.
