"Just received it today."

My only complaint is that they tend to be a one time use. The suction cups work well anywhere I have placed it it has not Fallen. It started working as soon as I put it in and has been working ever since. I guess these units do not like saltwater. So far, they're all doing their job in my four tanks and I am quite content.

"Very easy to read."

6 inch long Bala Sharks that are known to be very unruly and boisterous. Good cheap accurate aquarium thermometer. As you can see from my photos, in both°F and°C, all six are within. 2 deg, if it was 32, it would be a SOLID block of ice. I guess these units do not like saltwater. I had my heater set at 73-degrees and the thermometers showed 74. 6F all six took about three minutes to read between 88.

"7 reading."

I think the people who said the suction cup broke. The non-working ones still provide 2 batteries each AND. So far, they're all doing their job in my four tanks and I am quite content. My poor fish was in 86 degrees water for a month. This thermometer is spot on accurate. I have it in both my aquariums now. Sure enough the digital thermometer was way off by 6 degrees!

89 I could buy Six Thermometers with Six included batteries. I used these on a number of my aquariums that have discus fish in them.

"Great price too."

I have it in both my aquariums now. This company is taking the long term view of how to do business right. I can't say which is the most accurate and don't really care. I read some of the 1 star reviews and most of them are not about the product. We are using them to measure various temperatures inside and outside of a motorhome. I have to admit I had two reasons for buying six. The non-working ones still provide 2 batteries each AND.

Then is started to give a low reading, and it is not reading the correct temperature. Water tested with Autidefy brand for two hours. One of my aquariums is glass, and the other two are plastic. 6 in a pack, extra batteries, easy set up, great price. Personally I do not mind the way it looks in my aquarium.

My only complaint is that they tend to be a one time use. This company is taking the long term view of how to do business right. SIX Digital Thermometers with SIX batteries INCLUDED working so well. Far more accurate than the usual small glass ones or external LCD strips. I have this thermometer on all my tanks.

Simple fix, you adjust the thermometer within the suction cup and VIOLA! And is easily hidden behind a plant. It's kind of difficult to hide and keep out of the way.

You can use the thermometer with or without the plastic suction cup. I ordered a new one and it works GREAT! Ordered three of these and they do the job. 82 PER THERMOMETER with battery included.

"Only thing the battries."

Since it is a mercury thermometer, it is very accurate. It is about 6 inches in length and roughly an inch wide. It is large enough to see without being obtrusive. It works equally well on all of them. Far more accurate than the usual small glass ones or external LCD strips. Now if it falls into a sink full of water, it's not a problem. Ordered three of these and they do the job.

All were Close enough for a fish tank and other uses. The lid is textured aluminum, and the suction cups don't stick to that. The suction cups work well anywhere I have placed it it has not Fallen. It works equally well on all of them. Still a recommendation for me due to price and accuracy. So the extra units will always come in handy. My only complaint is that they tend to be a one time use.

The plastic from the suction cup quickly turned from a clear to a milky white. I used these on a number of my aquariums that have discus fish in them. I tested this in a cup crammed full of ice and some water. Love it, it's easy to read and keeps an accurate temp. For the price I'll probably end up putting these in all of my aquariums. It is always where yo last put it and it is very easy to see and read. Simple fix, you adjust the thermometer within the suction cup and VIOLA!
