Review on 🌡️ KETOTEK Digital Thermometer Temperature Gauge with Waterproof Sensor Probe for Aquarium, Car, PC case, Power Bank. Celsius/Fahrenheit LCD Display, °C/°F Support. Perfect for PC MODs. USB Powered. by Tyler Dorsey

Edit: April 2020: still chugging. Still accurate. Still very happy with them. Original review: What a nice little thermometer. I would give it 5 stars but my first one broke within an hour and installation is a pain. The replacement was sent the next day which is very nice. Tested on a calibrated source, it was within 0.2F of 60-90F, perfect for my aquarium. At this price I would happily buy a few more. Even if it's a royal pain to climb. I really want the manufacturer to use the hole in the back panel for the USB cable instead of the side exit and do something different with the latches on the sides. Obviously this is a panel mount device, but the side latches and USB cable exit make this impossible. While I fasten it with velcro. Imperfect but functional.
