VIVOSUN First Impressions
Fish and me happy.
The display can be set to Fahrenheit or Celsius. I have kept aquariums for about 45 years. The plastic from the suction cup quickly turned from a clear to a milky white. My poor fish was in 86 degrees water for a month. Very accurate, have checked it with other thermometers as well. I was using one of those ubiquitous cheap digital thermometers on Amazon. Put them all in the same tank and they read very close to each other.

VIVOSUN Final Thoughts
So we are ordering more.
He was moving slow in the winter and we realized he needed a heater! Who knows, whatever it was, it was revolting! I removed the batteries of the units I wasn't using right away. I used to have a large hang in the side tank that you couldn't miss. 49 thermometer that is 100% accurate. At least in the first 3 months of use. The temperature fluctuated a lot with it.
