capetsma Aquarium Thermometer Digital Fish Tank Thermometer Accurate Reptile Thermometer Temperature Gauge with Large LCD Screen

Works great. Very easy to see the display. I'm happy.

Easy to read numbers, accurate.

Aquarium thermometer is missing from order, there's a hole in the bag as shown in confirmation photo. I checked area leading to inporch & didn't find anything.

The clear display screen with black digits is impossible to read if affixed to a dark background, such as a beer fermenter which is what I'm using it for. I cut a bit of aluminum foil to back it with, which makes it useable, but I would need to do it more carefully to make it look nice. I suggest the manufacture include a rectangle of shiny silver Mylar which can be removed if someone really wants the clear look, although I can't imagine where that would be preferred over easy-readability.

I’ve had this on my 5 gallon Spec V tank for several weeks and it’s still working fine. I wouldn’t say the temp is dead accurate but seems to be fine within 1°-2°. Very slim and discrete which is great. Less bulk inside the tank is always a good thing

I have another aquarium thermometer where you can submerse the sensor underwater and it is less than or equal to this reader’s temperature. I’d consider it 9.5/10 accurate. However, the suction is very weak and it’s ease of read is 7/10.

Not sure how to change from C to F

Read some negative reviews and chose to cautiously try this one. I like the larger display. My experience is very positive. First. I wanted a simple no frills thermometer. This provides exactly that. No alarms etc. I just wanted to see the temp. I placed it out of the way in a corner of the tank. I can read it from four feet away. Perfect. Secondly the accuracy is within .5 degrees as verifiable using a digital probe… as compared to the “strip “ temperature thingy that came with the heater I got which read about two degrees too low. And, it came with a spare battery. Could not be more pleased 😀

I’ve tried a couple of different temperature gages inside with this one outside. The glass on my tank is really thick . It was only a point of a cel . Did put a bad review last week. Sorry take back my comment 👍🏽

The only good thing about this is it sticks to the tank well, I have tested this only because I didn't believe what it was reading, and it's way off so much so I have taken it down.if I could send it back I would looks like the bin is whete it's heading, back to the drawing board

The product was accurate as described to really please come to products

Absolutely useless yes gives the temperature reasonably accurately but adhesion to the tank is pathetic
