Bright blue display for the first day and now I cannot get a temperature to display after only three days of use!

Excellent device.
This device makes it easier to roughly check the temperature on my carboys on a daily basis. I still use a glass thermometer when taking gravity readings.

Very helpful.
Have a temp sensor on every carboy and bmb we have. Easy to keep track of where they are this way.

Not very durable
2 degree swings in temperature great for starting out, as you progress in the hobby these are a great starter for monitoring temp. Stickers if they stay wet too long (swamp cooler) separate and become useless.

Like a glove
Is how it fits on a Big Mouth Bubbler. Seems fairly accurate in that with an external reading of 52ish, I got an actual of 50.5 from thermometer directly in sample.

Laid out really well and easy to read. Only complaint is that the temps are kind of hard to see unless you shine a light on it. Would be nice if the numbers were a little brighter

Good, but not great
Nice looking thermometer, but not as easy to read as the other ones I own (continuous adhesive strips). I wouldn't buy it again.

The thermometer arrived on time. It fit on the big mouth carboy nicely. the numbers don't show up real well but good enough.

Is this thermometer for one use only?
Mario R on Aug 4, 2018
BEST ANSWER: You apply this to the outside of your carboy (glass or plastic) and you're good to go. It has adhesive on the back but is not meant to be pulled off and moved to another vessel. Do not store your carboys where they are exposed to extreme heat and they should last for years. Cheers.
Is there one place better than another to place it on the Bubbler?
A shopper on Dec 11, 2016
BEST ANSWER: I feel it is best to have the guage near the middle of the carboy where most of the wine is.
