LLC 43330972: Liquid Crystal Aquarium Thermometer Vertical

Get it! Cheap, simple, and reliable!

Very accurate works well

I really like the way this thermometer looks and works. Quickly adjusts to reflect the water temperature virtually immediately after it's applied to the tank. My favorite feature is that it's very easy to read. This is because not only are the size of the individual temperature indicator blocks and the brightness of the associated background colors perfect, but the numbers representing the temperature are crisp, black, and appear right inside the color blocks. Visually striking and extremely easy to read. And it's moveable! Good aquarium thermometer at a reasonable price point.

Only issue I had with this product was that it came completely unpackaged. It was as though the packaging was ripped apart and the thermometer was just floating around the mailing package, so I just don't know whether that was something in shipping or handling, but other than that it's easy to read and understand and it sticks well to the side of my tank. It's easy to put on and take off if you need to move it. I have had no other issues with the product, just the shipping.

Accurate and easy to use. Showed the same temp as the submerged thermometer and the house thermostat. Difficult to read without adequate light.

Very nice and good adhesive to the glass. Took it off and moved a few times,still sticks perfectly. Works with the glass and plastic tanks.

So yeah, as far as stick on thermometers, this is the best one I've used thus far. It sticks well, resists saltwater drips on it, and has very bright and clear numbers. Through 5mm glass it's temps match what my heater is saying.

Hard to find a reliable and accurate thermometer these days. Compared to our medical grade infrared thermometer (which has been the same as the doctor's office) when in surface mode, this thermometer is about 4-5 degrees high. Apparently I had my fish in 81 degree water when ideally they needed 76.
