"Suction cups are okay."

I've checked it against two other thermometers that are accurate. 6 inch long Bala Sharks that are known to be very unruly and boisterous. Works well in my betta tank, but provide a couple hours for it to read temp changes. When and if we run out of this batch, I'll instantly order another batch. You dont HAVE to stick the display onto your tank. Instead she sent a new package of two, both of which work. This company is taking the long term view of how to do business right.

Fluval 11206 Final Thoughts

"2-degrees."

I just wrote it off as a minor loss. My poor fish was in 86 degrees water for a month. Then is started to give a low reading, and it is not reading the correct temperature. Now that the chickens are grown, I have one out in the coop as well. 6F all six took about three minutes to read between 88. I've checked it against two other thermometers that are accurate. All were Close enough for a fish tank and other uses.

"Great product!"

The non-working ones still provide 2 batteries each AND. In this scenario it would probably get knocked loose a lot. Love it, it's easy to read and keeps an accurate temp. And is easily hidden behind a plant. Love it, it's easy to read and keeps an accurate temp. He acted aggressively towards it and so I ultimate ended up removing it due to that. Far more accurate than the usual small glass ones or external LCD strips.

"Perhaps it's my fault."

Very impressed, I have now had them in used for a month so far. My only complaint is that they tend to be a one time use. This thermometer is spot on accurate. So much easier than the ones that hang on the inside. Sure enough the digital thermometer was way off by 6 degrees! I have this thermometer on all my tanks. 6 inch long Bala Sharks that are known to be very unruly and boisterous.

"It sticks very firmly."

I needed a solution that was not breakable and these do the trick! I have this thermometer on all my tanks. The suction works for a month at a time- in pool and hot tub circulation. Since it is a mercury thermometer, it is very accurate. My 50+ eyes cannot read a regular tank thermometer without squinting. Ordered three of these and they do the job. I just wrote it off as a minor loss.

All were Close enough for a fish tank and other uses. I used these on a number of my aquariums that have discus fish in them. I don't think i'll ever be able to trust a digital thermometer again.

"So far loving it."

Personally I do not mind the way it looks in my aquarium. Simple fix, you adjust the thermometer within the suction cup and VIOLA! 89 I could buy Six Thermometers with Six included batteries. Personally I do not mind the way it looks in my aquarium. The plastic from the suction cup quickly turned from a clear to a milky white. So far, they're all doing their job in my four tanks and I am quite content. You can use the thermometer with or without the plastic suction cup.

"No issues."

I think the people who said the suction cup broke. The digital display itself is easy to read at a glance. Since it is a mercury thermometer, it is very accurate. I can't say which is the most accurate and don't really care. 2 deg, if it was 32, it would be a SOLID block of ice. Still a recommendation for me due to price and accuracy.

"Great product!"

I guess these units do not like saltwater. As you can see from my photos, in both°F and°C, all six are within. So versatile, I can read the temperatures literally anywhere. This thermometer is spot on accurate. 2 deg, if it was 32, it would be a SOLID block of ice. Now I'm getting back in on a much smaller scale with 3 gallon Acrylic Nano tanks. 50 thermometers, reads much easier and no suction cup residue, also looks better.

"2 degrees of each other."

One extra battery came with each unit. The digital display is nice and small as well. All are pretty accurate within one degree as claimed. I bent it a little bit and when I put it back it was perfectly fine. Checked with temp gun and the terrarium was on target at 88. The temperature fluctuated a lot with it. This is how you calibrate a thermometer.
