API 2343 First Impressions
"Changed to 5-stars now."Very impressed, I have now had them in used for a month so far. I ordered a new one and it works GREAT! I recommend gluing the suction cups in place where needed for long-term installation. I don't think i'll ever be able to trust a digital thermometer again. I came here to give this product a positive review. Have checked them against the glass thermometers and the accuracy is right on. One extra battery came with each unit.

API 2343 Final Thoughts
"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.

Superfish 669005 First Impressions
"Perhaps it's my fault."You can use the thermometer with or without the plastic suction cup. For the price I'll probably end up putting these in all of my aquariums. They are within a degree or two of other thermometers I've checked to compare them. I needed a solution that was not breakable and these do the trick! Only thing I don't love is how long the cord is. I'm pretty sure those reviewers have acrylic tanks. He acted aggressively towards it and so I ultimate ended up removing it due to that.

"Great little thermometer."The temperature fluctuated a lot with it. I ordered a new one and it works GREAT! Then is started to give a low reading, and it is not reading the correct temperature. 6 inch long Bala Sharks that are known to be very unruly and boisterous. These things are useful for a lot besides pet husbandry, too. It is my opinion that everyone should have these that are in the Aquarium Hobby. The non-working ones still provide 2 batteries each AND.

"2 deg of 32."I read some of the 1 star reviews and most of them are not about the product. Sure enough the digital thermometer was way off by 6 degrees!

MINDPET-MED Final Thoughts
"I must say."For something so cheap, they are working remarkably well. A bit large for anything smaller than 5 gallons, but that's to be expected. Love it, it's easy to read and keeps an accurate temp. When I set up my newest tank I will be getting another one of these. Still a recommendation for me due to price and accuracy. So much so that I purchased a second set of 6. And for the price you cant beat it.

"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.

"Perfect customer service."Who knows, whatever it was, it was revolting! These are the perfect size to be easily read while not being obtrusive. 2 deg, if it was 32, it would be a SOLID block of ice. I have this thermometer on all my tanks. My 50+ eyes cannot read a regular tank thermometer without squinting. Water tested with Autidefy brand for two hours. It's kind of difficult to hide and keep out of the way.

"No complaints."So versatile, I can read the temperatures literally anywhere. I can't say which is the most accurate and don't really care. Then is started to give a low reading, and it is not reading the correct temperature. A bit large for anything smaller than 5 gallons, but that's to be expected. These things are useful for a lot besides pet husbandry, too. A battery can last you up to six months, I'd say, but expect more like three. We are using them to measure various temperatures inside and outside of a motorhome.

"Not just for aquariums!"Bought the two pack of thermometers. I've checked it against two other thermometers that are accurate. I find that the temps are accurate, and this product gives added peace of mind. He acted aggressively towards it and so I ultimate ended up removing it due to that. Then she followed up again on that, asking if they had arrived and were okay. One of my aquariums is glass, and the other two are plastic. You dont HAVE to stick the display onto your tank.

"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.
