This is a convenient small digital thermometer for accurately reading the temperature of the aquarium. I have my 65 gallon community water tank, which helps me set up the appropriate temperature after I get a new Eheim heater that may or may not need to be calibrated to heat to the right temperature. I have checked this Zacro with a glass thermometer in the chemistry laboratory where I work, and it is correct. It is between 0.5 and 0.7 of the heater I set up, but this can be attributed to the movement of water from air pumps, filters, etc., and the proximity of the temperature probe of the Zacro to the actual heater. As long as my temperature is within the temperature range I want, I know I can go. The Zacro can be mounted on the glass surface of your tank through a sucker, the probe has its own sucker, and you can slide the probe wire up or down so that you can suck high or low probes in the tank, no matter what you like. I open mine, check the temperature regularly, and then turn it off to save battery life. Zacro itself is small and inconspicuous. I have my installation on the side, it is supplemented by a traditional aquarium thermometer, I have been in the aquarium for more than 25 years, it can be said that this small, very cheap piece of equipment is necessary to maintain the temperature, your fish needs it for their own health. So go buy one. You won't be disappointed.

I bought this for my hedgehog cage. I need to make sure it's warm enough for him so he doesn't try to hibernate. After doing some research, I ordered the thermometer. I thought it was mainly aimed at snakes and other reptiles, but it got my job done. It's super easy to figure out, and when you get it, it's actually ready. Since I got this, it has been used every day, and it works very well. I don't think anything can be done to make it a better product. I will recommend this product to anyone who needs to track the temperature in the pet cage.

* as usual, I used my hard-earned money to buy the product at the current price. In addition, I have nothing to do with anyone who may have made a penny in the purchase process. *. I'm just saying, I've had an aquarium for about 45 years. Under the right circumstances, this magnet thermometer is the best. This will make you wonder why no one has thought of it before. You can put it anywhere you want, and you can reposition it at will, and you can even move from one tank to another in a few seconds if you want. It's always where you put it last, and it's easy to see and read. In this respect, it is much better than the popular, cheap, convenient, discolored tape, which sticks to the outside of the tank like a piece of tape (it may also be more accurate than those tapes). It also defeats floating suckers that I can easily read but never find, or that, like 90% of all aquariums, never get stuck and fall to the bottom of the tank. I even prefer this thermometer to the fancy electronic digital thermometer, which needs an ugly and clumsy cable probe in the water tank. Don't we already have enough wires and hoses to untie? Remember, I said, "under the right circumstances." I put my Smarttemp thermometer in a 20-gallon tank and I use it to breed and raise babies, which is great. However, I guess the thicker the glass in the tank, the bigger the fish, the more grumpy the magnet will be.

I ordered this thermometer so that we can observe the water temperature of our fish. Our last fish died because the water was too cold. I ordered a heater to better adjust the water temperature. We'll join our fish soon. I don't want to get a fish until I test the heater. So far, the water temperature has risen by 10 degrees and remains there. The thermometer is easy to use, and the sucker is attached to the side of the acrylic tank, which is not a problem. The digital part is located on the outside of the water tank and is easy to read.

All my aquariums have these. The trick to reading the temperature is to look at the green box. This is the temperature now. The brown frame above is 1 degree high and the blue box below is 1 degree lower. If it's between numbers, you may see a mixture of colors, but figuring it out is simple and intuitive. This is also quite accurate. I checked my gun with a makeshift gun, and everything was right. If you need to reposition, it's no big deal. Just peel it off gently and put it where you want it to go.

I'm not sure I need 10, but. Every time I pass the mirror, I see this man with white curly hair, wearing a long lab suit, and his eyes madly glued these digital thermometers to these jars that keep coming to my house. So I think I need them! As for the objects themselves, the backing is not very difficult to remove. All you have to do is slide an uncut shabby nail under the top corner of the thermometer. Push the sticky end onto the specimen jar, just where you want it, when you drag a small flat bone, pestle, the dark side of the blade, etc., slowly down, so that it can stick well, without any wrinkles or bubbles. The thermometer is quite thick, so it's not difficult to put it where there are no bubbles, but if it starts curling or blistering, the owner may get angry, so do one of your jobs and stay away from the rack. Areas that exceed the indicated temperature are well highlighted, so even the low-lit areas around the dungeon are not difficult to read, which is good because they are not heat-resistant and it is not good to bring the torch too close. TLDR: if you need one, you need 10. Buy these. They may even keep you away from the shelves. Daniel Gabriel Ferrenheit would be proud.

Great product! It works well and is easy to use. But I hope it doesn't take long to close. I put it in the upper right corner of my 20 girls.

So far so good. I'm doing a good job. It was calibrated from the start. Very good price. Four dollars for two. We can't beat it.

It's definitely worth having, just an awe-inspiring design. I've tried to find a good thermometer, but so far, it's the best it's got. I can find another similar, but priced at 40.00. I like it out there, so I don't have to worry about cleaning. I'm going to buy another one soon. I hope these are the last, but so far it's not bad! Update 10-27-19B the other will not be long after, where the two are still working perfectly. You don't even have to change the battery. So far, the quality of the project has surprised me. Is still absolutely recommended to all fish owners.

I have reservations about buying this, but it's a great gadget. It tends to disagree with my inkbird humidity controller about 10%, which I need to figure out, but it seems to track the trend well. I need to try to calibrate it to see how accurate it is, but the temperature looks pretty good. It's been in my vivarium for about 2 months, and I don't think it's going to have any problems. I think they improved it because the leak seems to have disappeared. I have a tropical rain frog and a flying dart frog. I use artificial rain and fog to keep the humidity at 90 degrees. There is nothing wrong with this equipment.
