"I am new to the hobby."

Very impressed, I have now had them in used for a month so far. Now if it falls into a sink full of water, it's not a problem. I use a small flashlight if I don't want to brighten the area. So much so that I purchased a second set of 6. This little wonder allows me to see at a glance that everything is as it should be. I find that the temps are accurate, and this product gives added peace of mind. In the right situation this magnet thermometer is the best available.

POPETPOP Final Thoughts

"Subtracted from the tank."

Simple fix, you adjust the thermometer within the suction cup and VIOLA! He acted aggressively towards it and so I ultimate ended up removing it due to that. I use a small flashlight if I don't want to brighten the area. I use a small flashlight if I don't want to brighten the area. Now if it falls into a sink full of water, it's not a problem. He was moving slow in the winter and we realized he needed a heater! Works well in my betta tank, but provide a couple hours for it to read temp changes.

"I like the product."

Ordered three of these and they do the job. Set all six probes up in a terrarium with a constant temp of 88. At least in the first 3 months of use. My poor fish was in 86 degrees water for a month. If the digital display starts to get dim, it's time for a new battery. They are within a degree or two of other thermometers I've checked to compare them. Since it is a mercury thermometer, it is very accurate.

"And he is a betta."

Simple fix, you adjust the thermometer within the suction cup and VIOLA! Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK. When I set up my newest tank I will be getting another one of these. Works well in my betta tank, but provide a couple hours for it to read temp changes. So much easier than the ones that hang on the inside. I had my heater set at 73-degrees and the thermometers showed 74. The digital display itself is easy to read at a glance.

"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!

"No complaints so far!"

I find that the temps are accurate, and this product gives added peace of mind. Put them all in the same tank and they read very close to each other. Have checked them against the glass thermometers and the accuracy is right on. I have mine on my 60 gallon cube marine tank. I bent it a little bit and when I put it back it was perfectly fine. 6F all six took about three minutes to read between 88. I just wrote it off as a minor loss.

I ordered a new one and it works GREAT! The non-working ones still provide 2 batteries each AND. Far more accurate than the usual small glass ones or external LCD strips. Ambient room temperature measures 72. I have bought many many temperature gauges for my various fish tanks over the years. The non-working ones still provide 2 batteries each AND. Sure enough the digital thermometer was way off by 6 degrees!

"Fish and me happy."

It's kind of difficult to hide and keep out of the way. I used to have a large hang in the side tank that you couldn't miss. I have mine on my 60 gallon cube marine tank. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Ambient room temperature measures 72. I have mine on my 60 gallon cube marine tank.

"Currently maintains a 76."

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. So this is the extreme end of the high temperature range. Now that the chickens are grown, I have one out in the coop as well.

"All you need."

It is my opinion that everyone should have these that are in the Aquarium Hobby. I read some of the 1 star reviews and most of them are not about the product. 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.

"Great product!"

I just wrote it off as a minor loss. The only reason I didn't give this 5 stars is because my betta fish didn't like it. It is large enough to see without being obtrusive. It will make you wonder why nobody thought of it before. So much so that I purchased a second set of 6. I have kept aquariums for about 45 years. We are using them to measure various temperatures inside and outside of a motorhome.

"I placed it on the side."

Very impressed, I have now had them in used for a month so far. Then she followed up again on that, asking if they had arrived and were okay. The units each had a battery in place and situated for immediate use. And I just really started to doubt it. One extra battery came with each unit. I bought these for my dwc reservoirs. One of my aquariums is glass, and the other two are plastic.
