Aquarium Thermometer, Digital Touch Screen Fish Tank Thermometer with Large LCD Display, Stick-on Tank Temperature Sensor Ensures Accurate Reading for Aquarium Terrarium Amphibians and Reptiles

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 didn’t 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!

Love the style, I can look thru them and see the fishes. It is so nice to glance at my tanks and see that the temperature is OK, not too hot or cold. These thermometers will read a few degrees cooler than actual water temperature because they are taking temperature of the glass surface, no big deal! Today I checked tanks 77.9 degrees, other tank 78.2 degrees. At least I know my water temperature is about 80 degrees and all heaters are working.

Great product. Pretty spot on accurate. Love that I can set a high and low temp. It flashes when the temperature is too low or too high. I did read other reviews before buying and I noticed a lot of people said that the battery that already comes in it dies pretty quick. And mine died after 1 week of use. So I already had to put the back up battery in so thankfully it came with a backup.

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)

This was an impulse purchase for me. I really like it but here are some things you might want to know :* It’s 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.* It’s 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.* It’s super easy to read and appears very accurate ( I’m 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 I’m happy with the purchase.

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 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 it’s stuck like cement! I highly advise placing it on the front glass about 6” below the waterline.

The media could not be loaded. Bought this to replace my old crappy in-the-tank thermometer and I'm really glad I did! It works better than the other one and looks way better. It's super easy to use as well and pretty sweet that you can set a high and low temp.AND WAIT.... THERE'S MORE!They include an extra battery for when the original dies so you don't have to go looking for one right away! I've seen some people complain about that but it's whatever I guess. If you really can't find a spot to store one tiny extra battery then I don't know what to tell ya.
