"A solid five stars."So versatile, I can read the temperatures literally anywhere. At least in the first 3 months of use. You can not swivle the thermometer to face a certain way. I have this thermometer on all my tanks. For something so cheap, they are working remarkably well. This is my first 5 star review out of many many reviews on Amazon. I recommend gluing the suction cups in place where needed for long-term installation.

Zoo Med TH24 Final Thoughts
"I placed it on the side."I find that the temps are accurate, and this product gives added peace of mind. So much so that I purchased a second set of 6. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. This thermometer is spot on accurate. Very accurate, have checked it with other thermometers as well. So this is the extreme end of the high temperature range. When I set up my newest tank I will be getting another one of these.

Zoo Med HC-11 Final Thoughts
"Very accurate."The suction works for a month at a time- in pool and hot tub circulation. Checked with temp gun and the terrarium was on target at 88. I have to admit I had two reasons for buying six. So, in those cases, I find it easier to simply replace it. I have mine on my 60 gallon cube marine tank. The extra batteries where very much appreciated and came in handy. Put them all in the same tank and they read very close to each other.

"Appears to be accurate."Then she followed up again on that, asking if they had arrived and were okay. Only thing I don't love is how long the cord is. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Simple fix, you adjust the thermometer within the suction cup and VIOLA! We are using them to measure various temperatures inside and outside of a motorhome. I think the people who said the suction cup broke. So, in those cases, I find it easier to simply replace it.

Zoo Med TH-27 Final Thoughts
"Great product!"I use a small flashlight if I don't want to brighten the area. As you can see from my photos, in both°F and°C, all six are within. Since it is a mercury thermometer, it is very accurate. They reviewed the packaging or shipping by saying it arrived broken. One extra battery came with each unit. 89 I could buy Six Thermometers with Six included batteries. You dont HAVE to stick the display onto your tank.

"I like these."This temperature read a perfect 32 degrees. I have this thermometer on all my tanks. 89 I could buy Six Thermometers with Six included batteries. The non-working ones still provide 2 batteries each AND. The digital display itself is easy to read at a glance. A bit large for anything smaller than 5 gallons, but that's to be expected. I used these to raise chicks, and in my parrot cages.

"Works perfect."I don't think they are backlit but for the price they are still nice. The digital display is nice and small as well. I got root rot after light leaks and high water temps. I have it in both my aquariums now. 89 I could buy Six Thermometers with Six included batteries. When and if we run out of this batch, I'll instantly order another batch. One extra battery came with each unit.

"They are within 0."SIX Digital Thermometers with SIX batteries INCLUDED working so well. I have always had trouble reading the color temp. You can use the thermometer with or without the plastic suction cup. Now that the chickens are grown, I have one out in the coop as well. SIX Digital Thermometers with SIX batteries INCLUDED working so well. This thermometer is spot on accurate. I got the second one as a bonus that I'm now using in my old tank.

"Working wonderfully!"I'm pretty sure those reviewers have acrylic tanks. It will make you wonder why nobody thought of it before. Very impressed, I have now had them in used for a month so far. I can't say which is the most accurate and don't really care. I came here to give this product a positive review. This is how you calibrate a thermometer. My 50+ eyes cannot read a regular tank thermometer without squinting.

"These are great!"Water tested with Autidefy brand for two hours. So far I've been very thrilled with these. Since it is a mercury thermometer, it is very accurate. 6F all six took about three minutes to read between 88. So much easier than the ones that hang on the inside. The suction cups work well anywhere I have placed it it has not Fallen. A bit large for anything smaller than 5 gallons, but that's to be expected.
