I love it

I'm not sure how accurate it is. I dont have another thermometer to check. What I DO know is that its measuring the temp to be approx around the temp my little heater is pre-set to heat for. I have 2.5 gal tank with 1 betta. The heater I bought is meant to keep the tank at 78 degrees and shut off, turning on only to maintain that temp. From reviews I read it keeps the tank more around 74-76 degrees. The temp sticker is exactly at that point which makes me believe its accurate. I also love the size of it and the fact that it ISNT in the water.

Accurate and readable.

Over the years I've used all kinds of thermometers for my tanks, and this kind is the most accurate, readable, and trouble-free, when they work, and this does. The cheap ones are worthless, however, and a waste of money. I like that this is a small clean design in F* only, and is indeed accurate. I wish that it went a bit higher than *82, but for the tank it's on it shouldn't be problem.

Not accurate for me

Reviewed in the United States on February 29, 2020

The thermometer I received is very inaccurate. I am not sure if it is because my tank is plastic or if the thermometer I received is defective. The thermometer tends to read 68-70 most of the time and other thermometers when placed in the tank read 78 which is what the tank heater is set at.

I ultimately purchase this Thermometer after reading many reviews for many different Thermometers. I purchased this for $4.99, and so far it is great. Easy to Read, fast results. Very happy overall. Great for our starter tank!

Bought this for my office desk aquarium which is plastic and 1.6 gal, so pretty small. This thermometer sticks nicely to the side and does look obtrusive at all and seems to be doing a great job. It is about 3.5" long which is far more petite than the xl ones at the big box stores.

Small and readable temp

Reviewed in the United States on June 9, 2019

Can actually move this but I wouldn't more then once because of adhesion. Fairly accurate and very easy to read unlike others. I prefer the short, wider style over others who are long and skinny. Good deal too!

surprisingly easy to read

Reviewed in the United States on April 4, 2012

I wanted this thermometer to make sure I was in the ideal temp range for my betta's aquarium. Between hot summers and chilly winters, I wanted to be sure my heater was doing it's job AND there was appropriate cooling and AC in the room.

I put the sticker on the outside bottom left corner of the front face of the 2.5gal tank. At first I was a bit worried the sticker was too big-looking but it looks great and I'm so used to it now! The temp is easy to read and seems to be accurate- it does reflect variation between 78 and 80 degrees, so it's not stuck or anything...

Would definitely recommend. Esp at the price- maybe two if the tank is big or you need to remove and replace or something XP

Works well and nice (small) size for little tanks.

After buying 2 different stick on thermometers that did not work, I ordered one of these and it works perfectly. It fits the small tank much better than the ones that were twice its size. Very happy with this purchase!
