Review on VIVOSUN 2-Pack LCD Digital Aquarium Thermometer Fish Tank Water Terrarium Temperature Gauge with Suction Cup for Turtles by Sheila Golden

I was looking to buy a similar unit locally and saw it online and for the same price you get two in a pack! That in itself is a lot! Both devices worked great out of the box. Mine already had batteries and was on, although I assumed it was because it was tested before shipping (and hopefully no return). The suction cup was so-so at first and fell off a few times, but after settling into our home it is now taking root and holding up well. I used this in my daughter's 10g tank and the other is used in my wife's nano shrimp tank. The accuracy I would say is pretty good and close to the actual temperature of the aquarium. Overall, I would recommend this to anyone looking for a budget digital thermometer.
