## Description

desertcart.com : NEPTONION Aquarium Thermometer LCD Digital Aquarium Thermometer with Suction Cup Fish Tank Water Terrarium Temperature for Fish and Reptiles Like Lizard and Turtle : Pet Supplies

Review: Good product - This worked for many 6 years and I liked this product. I would buy this one again.
Review: Good budget digital thermometer - Unit is good for what it is and appears to be accurate enough for my needs. I like that it comes with the batteries and suction cups for both the unit and the probe that attaches inside the aquarium. I normally just turn it on as needed when I want to view the aquarium's temperature and then shut if off to conserve batteries. Temp accuracy-wise, I'd say it is not spot on, but close enough when I compare it with other thermometers when checking the water temps. Time will tell how sturdy the button is with all this turning on and off, but in my case, I would only check the aquarium's temp once or every other day or so, as I also have a standard glass thermometer inside the aquarium. Overall a good buy and worth it.
