JW Pet 21600 First Impressions

Working wonderfully!

These digital thermometers are great and there is no guesswork involved. So the extra units will always come in handy. Since it is a mercury thermometer, it is very accurate. I did have a problem with one in my first pack of 6. I have mine on my 60 gallon cube marine tank. Only thing I don't love is how long the cord is. When and if we run out of this batch, I'll instantly order another batch.

JW Pet 21600 Final Thoughts

I like this.

I used these on a number of my aquariums that have discus fish in them. It works equally well on all of them. Very impressed, I have now had them in used for a month so far. So far, they're all doing their job in my four tanks and I am quite content. So this is the extreme end of the high temperature range. I have to admit I had two reasons for buying six. The extra batteries where very much appreciated and came in handy.
