    Inconsistent performance and quality.
  

*by D***N on Reviewed in the United States on September 22, 2017*

I initially loved these small, inexpensive thermometers.  I have purchased several.  They are inexpensive, small, easily positioned, easily moved between tanks, and easily read outside the tank.  Unfortunately, in my experience, many of them are inaccurate and some of them are highly inaccurate.Although I have bought a few different brands, they all look exactly the same and I can only conclude that there is likely just one contract manufacturer stamping different brands on their product.  Unfortunately, I have found significant inconsistencies in these devices, regardless of brand.  In my experience, if I put 8 of these (this brand and others) in the same aquarium at the same time and in roughly the same spot, I will get 5 - 8 different readings.  Many of those readings will be fairly close, say within one-half of one degree, but some will be more than a full degree off and some will be several degrees off from the majority.  When compared with a traditional thermometer, I find that most of the digitals are within one-half of one degree, but again, several are one+ degree off with a few being way out of alignment.Based on my experience and informal testing of about 8 - 10 units (from various brands, including this one), I cannot recommend these digital thermometers for applications that require precision within less than about one-half of one degree -- and, even then, you have to check your thermometer regularly to ensure it is measuring within that range.If anyone has found a highly consistent and accurate digital thermometer for aquarium use (FW), please let a comment below with your recommendation.  I need several.  Thanks.

    Inaccurate, Verify readings with LFS before use
  

*by L***I on Reviewed in the United States on August 19, 2016*

Inaccurate. Purchase at your own risk, but do me a favor and have them verified by a local fish store if you plan to have this as your sole temperature gauge in your tank.  My reef tank runs a little warm, right around 80F (as per a mercury thermometer). As soon as I put these in, they read 76.3F.  I took them to a fish store that i trust, and has expensive tank management equipment, and they verified it was ready over 4 degrees too cool for their tanks, which they keep at 78.  I have considered using them and just adding 4 every time i check it, but my concern is that they are not just miscalibrated, but actually read temperature incorrectly all together.  It is not in my tank at all.  I will spend more money and a reliable one from my LFS.!!PLEASE do not rely on this product to regulate your aquarium until you verify its accuracy.  while it is possible yours is working accurately, its also possible you are setting your tank too hot or too cold and stressing your fish out, possibly even killing them.!!

    Great for a general reading of your tank, if you want exact temps...look elsewhere!
  

*by J***P on Reviewed in the United States on May 1, 2018*

Bought this particular brand because most reviews stated they were more accurate than other offerings.Using these as a quick reference to my tank temps and for that purpose they’re great.I have two in the same tank and the variance between the two is about 2 degrees. That being said, I recommend not using this as your sole thermometer if you are trying to obtain exact temp readings; you’ll need something else.I have a glass floating thermometer in the tank as well to verify any readings if needed.Other observations...-The suction cup on it isn’t great, but most suction cups on aquarium parts fail at some point anyways.-If you want it totally secured, you will need to use double stick tape or velcro. There is a slot in the back that accomodates a screw or nail if you are not putting it on the tank itself.-The temp probe needs to be weighted or secured with the supplied inline suction cup otherwise it will just float around.-I have had no problems turning mine off by holding the power button down for a few seconds. Turning it off defeats the purpose of why I bought this though, so I keep it on 24/7.Hope my review helps!
