Customers say
Customers find the thermometer extremely accurate, with one noting it consistently tracks to within 0.2F, and appreciate its large, easy-to-read display that can be seen from across the room. They describe it as a great digital thermometer that’s super easy to use, taking just 20 seconds to install, and like its appearance. The functionality receives mixed feedback – while some say it works great, others report it stops working after a month. The read accuracy and battery life also get mixed reviews, with customers noting it reads 1-2 degrees lower than actual temperature and consumes batteries quickly.

Awesome, looks good, I just need 19 more!
I love this thing. I’ve been trying to find a good, reliable and sticky thermometer for my tanks. I have about 20 and am tired of the cheap ones failing out falling off, then out, of the tank. They also fail often, never last long, sometimes change tempature readings from f to c without me asking. Not to mention accuracy! It’s awful. I care too much about my little fish friends, shrimp, plants and yes, snails lol… To play the “I hope the temp is close” game.I wasn’t sure I wanted to spend this much on a thermometer for every tank but recently I had new heaters in 3 tanks that failed. I ordered a few different thermometers to try, one failed immediately. This one is accurate, looks good, super easy to use!!!! Seriously! Under a minute to read the instructions then had my too high and too low temps set. I feel better just having that alarm option.I’m definitely going to be getting these for all my tanks, a couple every month. It’s worth it.If I could change one thing it would be that this meter light up brightly when the alarm is going off… Finding out which tank is beeping will be amusing lol! I’m not the only multi tank hobbiest, it would help immensely!I will update this, as I always do, the moment anything changes. I want my feedback to remain accurate since it’s how I make a choice on products here (have you read the reviews on heaters?! Does anyone make a reliable aquarium heater? Good grief lol)

Accurate Reading with an added feature!
Best Aquarium Thermometer! AccurateIâve had this side by side to a thermometer that actually goes into the tank and gives me an exact reading. This little device is costly, but comes with an extra battery to keep it on AND fits so nicely and hidden away on the side of my fish tank. I almost forgot to mention it comes with a feature to set a high and low temperature for the tank of where it should be at its highest and lowest and iâll blink letting you know something is off. Purchased this for my 10G betta fish aquarium who needs the temp to be between 78-81 at all times. I placed it on the side of my aquarium where I also place his food and take a look every morning. Definitely worth a buy !

Aquarium thermometer
A pretty good product but the battery can become loose and give false readings. Even after carefully installing the battery in the locked in position. if the housing gets bumped, the battery can become loose. I would recommend installing the thermometer on a side of your tank but not on the front where you may bump it while cleaning or feeding your fish.

Things to consider
This was an impulse purchase for me. I really like it but here are some things you might want to know :* Itâs not tiny and on a nano tank it takes up some room. I placed it on the side.* It reads the water temp through the glass. There are no sensors placed in the water.* It sticks on the outside of the tank with included double sided tape. It sticks very firmly. They do not include extra tape so it might be an issue in future.* Itâs not marked waterproof and does not seem waterproof. I would try NOT to wet this item.* An extra battery is included.* The set up instructions on the package are vague and confusing. The best instructions are written on amazon with the ad for this item.* Itâs super easy to read and appears very accurate ( Iâm using it along with a standard in water temp monitor )*You will need another way to check water temps in bucket when your adding water to your tank.Overall , I love it and Iâm happy with the purchase.

Stylish and Functional
Looks great, easy to read, easy to set up, only one of the batteries worked so thankful that it came with an extra because the original one didnât work anymore. Sticks to the aquarium easily.This seems to accurately measure temperature and has a neat alert feature if the temps go too high or low based on your settings. Very happy!

very frustrating
the only good thing about this product is that it is aesthetically pleasing. the cons are as follows:- never made steady contact with the glass. always lost connection with the glass unless i was applying pressure to the adhesive part.- since it always lost connection/ reading the glass is always reset. every time it loses connection it resets to celsius, so i could never read it correctly without having to touch it and adjust it back to Fahrenheit.- every time i touched it to get it back to Fahrenheit, it would zero out again because once i removed the pressure from the device it lost connection with the glass.- and now after using it for officially one month it is completely dead. what a waste of time & money & now i get to go rush & try to find another thermometer for my aquarium. lame product.

Nice, but hard to see.
Nice temp gauge but very hard to see in daylight. If only it would light up this would get 5 stars. One you stick it to the aquarium glass itâs stuck like cement! I highly advise placing it on the front glass about 6â below the waterline.

Wow, this has been amazing. I had a heater go rogue on me and continue heating my tank up to nearly 90 degrees before I figured out why everything suddenly looked so awful! I have extremely limited space (my tank takes up the entire cabinet top with not so much as a quarter inch left over) and didn’t want something dangling in my display so I decided to give this a try. It’s very large and the image is very crisp/easy to see, so if you put it on your main viewing surface, it may be a bit of an eyesore, especially on a small tank. But I run a AIO and mounted this to the glass along the sump, where you look straight through to the black inner chambers. This really dims down the reading and makes it extremely unobtrusive, while still being perfectly legible. I absolutely love being able to glance at the tank and tell what the temperature is, and every time I’ve tested it, it has been spot on. If you’ve got a dark/out of the way corner of your tank to stick this to, go for it!

Nice thermometer for tank, like the look of it, is bigger then i expected but it works well and is easy to read.

This thermometer works perfectly, & will never be knocked off the tank side by boisterous fish. You do need it to be back lit by the tank lights to see the temperature, however if you get close enough in daylight itâs fairly easy to see.Comes fitted with a battery and a spare. Gets a solid 9 out of 10 – would be a 10 if it had its own light, but I think this would drain the battery too quickly.

Funciona muy bien en mi pecera y si se puede ver lo que hay detrás del panel de lectura

Después de tener varios termómetros que marcan dos grados mal, este es más preciso, a parte que la tortuga tiene más espacio en el acuario, estéticamente para peces puede que sea muy grande pero a mi para mi tortuga me parece el mejor. Coincide exactamente con la temperatura que tiene el calentador.
