Marina ThermoSensor In-Out Thermometer

The description says "Provides both inside and outside aquarium temperature readings"

This description is wrong or poorly worded. The device only provides 1 temperature! I'm guessing what it means is it can be used for either inside or outside your aquarium. This is still a great product however, just don't expect to have both temperature reading for your room and inside your aquarium.

I've owned this for a couple months so far and it appears to work well up till this point. I have a temp gun which I used to check the reading this was telling me. They matched up well. Between the price and how accurate it is thus far it is worth it. I use it to read the temperature between egg flats, so the temp gun won't work for that application.

This thermometer is great except it stopped giving an accurate reading. Now it varies anywhere between +/10 degrees! Beware!

Perfect! only wish the cord was a little longer, other then that 5 stars! The temperature was perfectly calibrated and matched up with the regular mercury thermometers I have in it as well. Highly recommended!
