Imagitarium THM-008 First Impressions

"Super easy."

The extra batteries where very much appreciated and came in handy. It is easy to use and install it'disappears' in your tank it is so unobtrusive. Set all six probes up in a terrarium with a constant temp of 88. The non-working ones still provide 2 batteries each AND. I use a small flashlight if I don't want to brighten the area. Was going to get a floater until I saw this magnetic one! I tested this in a cup crammed full of ice and some water.

Imagitarium THM-008 Final Thoughts

"I opened the first three."

The display can be set to Fahrenheit or Celsius. I have to admit I had two reasons for buying six. And I just really started to doubt it. The only reason I didn't give this 5 stars is because my betta fish didn't like it. If the digital display starts to get dim, it's time for a new battery. Since it is a mercury thermometer, it is very accurate. Checked with temp gun and the terrarium was on target at 88.

"Buy these."

These things are useful for a lot besides pet husbandry, too. In this scenario it would probably get knocked loose a lot. 2 deg, if it was 32, it would be a SOLID block of ice. I guess these units do not like saltwater. I just wrote it off as a minor loss. The units each had a battery in place and situated for immediate use. I am extremely pleased with this product.

3. Inkbird Dual Probe Thermometer for Fish Tank, Water Terrarium Only for C929-A Probe

Inkbird First Impressions

"2-degrees."

Set all six probes up in a terrarium with a constant temp of 88. I can't say which is the most accurate and don't really care. If the digital display starts to get dim, it's time for a new battery. These digital thermometers are great and there is no guesswork involved. These are the perfect size to be easily read while not being obtrusive. Place it on your aquarium and you are good to go. I find that the temps are accurate, and this product gives added peace of mind.

"So far so good."

And for the price you cant beat it. I recommend gluing the suction cups in place where needed for long-term installation. The non-working ones still provide 2 batteries each AND. So much easier than the ones that hang on the inside. This little wonder allows me to see at a glance that everything is as it should be. So far I've been very thrilled with these. Who knows, whatever it was, it was revolting!

"The hotter, the faster."

It is always where yo last put it and it is very easy to see and read. So this is the extreme end of the high temperature range. The digital display itself is easy to read at a glance. Excellent working for our bearded dragon tank. They are within a degree or two of other thermometers I've checked to compare them. Have checked them against the glass thermometers and the accuracy is right on. Excellent working for our bearded dragon tank.

"So we are ordering more."

I was using one of those ubiquitous cheap digital thermometers on Amazon. I have this thermometer on all my tanks. A bit large for anything smaller than 5 gallons, but that's to be expected. These are the perfect size to be easily read while not being obtrusive. Far more accurate than the usual small glass ones or external LCD strips.

"2 degrees of each other."

It is always where yo last put it and it is very easy to see and read. I have bought many many temperature gauges for my various fish tanks over the years. I bought these for my dwc reservoirs. I've checked it against two other thermometers that are accurate. The suction cups work well anywhere I have placed it it has not Fallen. Simple fix, you adjust the thermometer within the suction cup and VIOLA! My 50+ eyes cannot read a regular tank thermometer without squinting.

"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.

"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.
