"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.

"There is no question."

The only reason I didn't give this 5 stars is because my betta fish didn't like it. And for the price you cant beat it. I needed a solution that was not breakable and these do the trick!

"Love it for my turtles."

2 deg, if it was 32, it would be a SOLID block of ice. 6 inch long Bala Sharks that are known to be very unruly and boisterous. It is about 6 inches in length and roughly an inch wide.

"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.

"A solid five stars."

I don't think they are backlit but for the price they are still nice. So far I've been very thrilled with these. 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. I have it in both my aquariums now. It works equally well on all of them. The suction works for a month at a time- in pool and hot tub circulation.

"Would buy again."

In the right situation this magnet thermometer is the best available. The extra batteries where very much appreciated and came in handy. It worked great and I highly recommend it! I have to admit I had two reasons for buying six. I don't think i'll ever be able to trust a digital thermometer again. I used to have a large hang in the side tank that you couldn't miss. This little wonder allows me to see at a glance that everything is as it should be.

"Very accurate."

This little wonder allows me to see at a glance that everything is as it should be. Personally I do not mind the way it looks in my aquarium. You can not swivle the thermometer to face a certain way. I removed the batteries of the units I wasn't using right away. So far, they're all doing their job in my four tanks and I am quite content. For something so cheap, they are working remarkably well. This doesn't bother me as it ws so cheap.

"So we are ordering more."

I bent it a little bit and when I put it back it was perfectly fine. 82 PER THERMOMETER with battery included. Since adding one of these, it has been much easier to monitor the temp of my tanks. Sure enough the digital thermometer was way off by 6 degrees! It works equally well on all of them. It's kind of difficult to hide and keep out of the way. I have always had trouble reading the color temp.

"No complaints."

I guess these units do not like saltwater. Only thing I don't love is how long the cord is. Since it is a mercury thermometer, it is very accurate. The non-working ones still provide 2 batteries each AND. Put them all in the same tank and they read very close to each other. We are using them to measure various temperatures inside and outside of a motorhome. In the right situation this magnet thermometer is the best available.

"Fish and me happy."

However, Lucy at Zacro read this review and emailed me. The only reason I didn't give this 5 stars is because my betta fish didn't like it. I recommend gluing the suction cups in place where needed for long-term installation. It is my opinion that everyone should have these that are in the Aquarium Hobby. I got the second one as a bonus that I'm now using in my old tank. In the right situation this magnet thermometer is the best available. When and if we run out of this batch, I'll instantly order another batch.

Was going to get a floater until I saw this magnetic one! I have it in both my aquariums now. I can't say which is the most accurate and don't really care. So far I've been very thrilled with these.

Very impressed, I have now had them in used for a month so far. I have to admit I had two reasons for buying six. They reviewed the packaging or shipping by saying it arrived broken. Ambient room temperature measures 72. I needed a solution that was not breakable and these do the trick! And I just really started to doubt it. Then she followed up again on that, asking if they had arrived and were okay.

"Never had any problems."

I did have a problem with one in my first pack of 6. For the price I'll probably end up putting these in all of my aquariums. You can not swivle the thermometer to face a certain way.

Simple fix, you adjust the thermometer within the suction cup and VIOLA! Very accurate, have checked it with other thermometers as well.
