Review: Works super well! - Everything works well! I really liked that this package came with 2 working batteries so I didn't have to go on a scavenger hunt to find these certain batteries. My fish loves to squeeze into every small space possible and so she's managed to separate the heater from the wall, but she's yet to accomplish that with these suction cups! The thermometer works super well, I only wish there was an LED option where it's easier to read. When the lights are on, it's legible, but at night when everyone is most wary of leaving their heaters on, I can't read it so I'm always using the flashlight on my phone to read the numbers. Only a slight inconvenience, but not large enough to hate on it. I've only had it for 4 days now, but it works super well and I love that it's small! Update: it's been over a month since I've bought it and I've yet to have any issue with it overheating. Occasionally, I may notice that it's a little warm (if it gets to be near 83 degrees, that's when I open a window or something, I don't use the AC or heater in my apartment). I have yet to unplug it other than when I clean the tank!
Review: Easy to use - Don’t mind my green tank! This was very easy to use and set up. You can do Celsius or Fahrenheit. You simply put the probe halfway down your tank in the water so you keep an accurate temperature status and put the other side on the outside of your tank and you can keep track of your temperature digitally. This is important because we are getting an axolotl and you have to keep the temperature cold so we wanted something that would be extremely accurate for his environment. I think it is extremely easy to set up and great for any beginner to be able to keep track of their tank temperature. I give it five stars because it is so easy to use and it’s extremely accurate from everything that I have been able to check.

### ⭐⭐⭐⭐ Revised - Started Working After a New Battery
*by P***S on September 5, 2020*

At first the thermometer was not working - just kept reading 79.6. Decided to clean the tank and noticed the numbers on this one was hazy (had not removed it yet since was suction cupped in). I replaced the battery just to see and sure enough it started working. So - if you don't see the numbers moving replace the battery. Don't know if it was due to the original battery being a problem or if it was reset by replacing the battery.
