"The hotter, the faster."If the digital display starts to get dim, it's time for a new battery. Works well in my betta tank, but provide a couple hours for it to read temp changes. Have checked them against the glass thermometers and the accuracy is right on. These are the perfect size to be easily read while not being obtrusive. So, in those cases, I find it easier to simply replace it. Put them all in the same tank and they read very close to each other. One extra battery came with each unit.

Lifegard Aquatics R800204 Final Thoughts
"It's accurate I tell you."Since adding one of these, it has been much easier to monitor the temp of my tanks. I have kept aquariums for about 45 years. Ordered three of these and they do the job. When I set up my newest tank I will be getting another one of these. For something so cheap, they are working remarkably well. SIX Digital Thermometers with SIX batteries INCLUDED working so well. This little wonder allows me to see at a glance that everything is as it should be.

"Which is good."So the extra units will always come in handy. The suction works for a month at a time- in pool and hot tub circulation. Now if it falls into a sink full of water, it's not a problem. It is large enough to see without being obtrusive. Place it on your aquarium and you are good to go. And I just really started to doubt it. I had my heater set at 73-degrees and the thermometers showed 74.

"Close enough I reckon!"I recommend gluing the suction cups in place where needed for long-term installation. A bit large for anything smaller than 5 gallons, but that's to be expected. I use a small flashlight if I don't want to brighten the area. My poor fish was in 86 degrees water for a month. The only reason I didn't give this 5 stars is because my betta fish didn't like it. So this is the extreme end of the high temperature range. Just BE CAREFUL WHEN ADJUSTING, IT IS GLASS AND WILL BREAK.

"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.

"2 deg of 32."This company is taking the long term view of how to do business right. I have to admit I had two reasons for buying six. I bent it a little bit and when I put it back it was perfectly fine. I recommend gluing the suction cups in place where needed for long-term installation. So the extra units will always come in handy. I had my heater set at 73-degrees and the thermometers showed 74. I had my heater set at 73-degrees and the thermometers showed 74.

"It works great."He was moving slow in the winter and we realized he needed a heater! 6 in a pack, extra batteries, easy set up, great price. The lid is textured aluminum, and the suction cups don't stick to that. Since adding one of these, it has been much easier to monitor the temp of my tanks. The temperature fluctuated a lot with it. I am extremely pleased with this product. My poor fish was in 86 degrees water for a month.

"The hotter, the faster."I've checked it against two other thermometers that are accurate. Love it, it's easy to read and keeps an accurate temp. A bit large for anything smaller than 5 gallons, but that's to be expected. A battery can last you up to six months, I'd say, but expect more like three.

"I like these."I removed the batteries of the units I wasn't using right away. Bought the two pack of thermometers. Good cheap accurate aquarium thermometer. The plastic from the suction cup quickly turned from a clear to a milky white. It is always where yo last put it and it is very easy to see and read. The non-working ones still provide 2 batteries each AND. All are pretty accurate within one degree as claimed.

"So far so good."For something so cheap, they are working remarkably well. I can't say which is the most accurate and don't really care. This temperature read a perfect 32 degrees. The suction will never be the same. This doesn't bother me as it ws so cheap. So, in those cases, I find it easier to simply replace it. Only thing I don't love is how long the cord is.
