Purchased this product last time it was on sale, put it in the kettle at mash in as advertised, and it exploded, causing my brewday to come to a screeching halt. Would not recommend

Poor product
It is not accurate enough to monitor fermentation temperature; it read 14 degrees lower than two other thermometers I tested against: one was a spirit thermometer and the second was an electronic thermometer (the probe of which I had calibrated in boiling water). All three thermometers were submerged in a large stainless beaker. The water was stirred and the readings were taken after each had reached an end-point (quickly for the electronic probe, but to be sure, I waited an additional 10 minutes to take a reading on the others).

Even if it were accurate enough, it would be difficult to read precisely as the nominal 4" scale covers 200F. As I bought the thermometer from morewinemaking, I had assumed it would be useful for wine, but not, at least the way I know to make wine.

I've made many purchases from this company and this is the first time that I have been let down by the product itself. Excluding this purchase, I would rank it a 5-Star outfit.

It served a purpose
I used to use it in my MLT to be able to open the lid and not have to wait for a new temp check to stabilize. I would do a side by side quick calibration to make sure the numbers match and if not, determine a correction factor and keep it in mind for future use. I recently broke mine, but it was to no fault of the fragility of the glass, I just messed up in handling it.

unreliable thing
The same situation - bad quality, thermometer was broken when i was getting water to boiling with crashed glass and many little metal balls on the bottom. Fortunately, there was no grain in the mash tun.
