LCD Digital Aquarium Alarm Thermometer, Large Screen Transparent Fish Tank Thermometer, Always Monitoring Your Water Temperature - Fast & Accurate - No Messy Wires

Nice little thermometer, have one of these on each of my three tanks. Nice simplistic design and blends right in with the tank. As far as I can tell they're accurate enough within a degree or two. Only thing that I will advise is the battery life is not so hot, maybe 2 months before you have to change it. So just grab a pack of batteries to have on hand, other than that good product.

It works great for my aquarium, accurate compared to sticker thermos, i am using it on a 12mm/0.47" glass.

I’ve had this for about 2 months and I’ve already had to change the battery. It’s a little hard to read the temperature at times or have to be right in front of it. I have it at the bottom corner of my tank so maybe that’s the reason. But it still works and does the job.

I like it so much had to have one for each tank,they look nice and are easy to read. I was able to remove one off a tank that i was not using and reattach it to another tank without a problem. However, I took one star off because they seem to be off by +/- 1 degree, both tanks are at 77f accornding to my calibrated thermomiter and both read about a degree colder , but they work and are easy to read, over all I like them.

Out of the box it did not function.Installed the 'so-called- extra battery because the one already installed was dead.The digital display was missing at the top of the screen.Then I noticed that the depressions in the plastic packaging tray was meant to house both batteries.Of course that means that the item had already been used, battery drained, and now sent out to lucky me.Another case of someone (Amazon?) selling a returned and faulty item.This was not worth the packaging tape and time sending it back, however I am returning it because a $15 simple aquarium thermometer should just work.

I used to use this thermometer on all my fish tanks ( strip ones),some times I wasn't sure if they were working right,now with this other thermometer game changer,thank you guys for this new concept.

Stopped working after 2 months. Screen flashes and doesn't read temperature. I never got it wet and even replaced the battery. It still does not work. Save your money for something else because this product is not worth buying.

Its as good or better than more expensive products.
