Accurate reading
Works as designed, great purchase. Reads temp quickly, fairly accurate (+/-) 2 degrees. Wish it had a backlight, but I guess that would drain it’s lil battery quicker than without that feature.

Great works well accurate
The accuracy of these are great. Works way better than the sticky ones. You can also switch from Celsius to Fahrenheit easily. No set up really just pull the tab out of the battery put the suction cups on both ends stick the display on the outside of the tank and the wand inside.The inside suction cups keep falling off. That is my only complaint I guess. Although not really an issue. Just doesnât look as neat. Iâve only had these for a month or so and the battery is still going strong. But would be easy to replace. Great value for money. Built good enough for what it is. If needed I would buy these again. Wish you could give half stars would give 4.5 stars!

First batch I bought great. second batch all reads and
I bought these a year ago for my fish tanks and they work perfectly. I need it two more so I decided to buy a whole package cuz it’s cheaper. For some reason this package seems to be off by 2 to 4° sometimes. Sometimes it said my water was 77 when it was really 82. Sometimes it said my water was 78 when it was 80. I was keeping an eye on the water temperature and it’s late at 77 so I put a manual thermostat in there in the water was 83°. My other batch I bought a year ago, they all work fine. they all match what the manual thermometer. For some reason these ones do not. The first batch I bought of these were great the second batch not so much so I threw them all in the trash and I need to replace them not sure if I’m going to buy from this company again or try a different one but disappointed

Great thermometers!
These are great for the money! I have them in my aquariums and they do a wonderful job!

Accurate enough
I run a 60 tank fishroom breeding many different species of fish. I have been buying anogher brand of digital thermometers. I always lay them all out and usually have to throw a couple away that are several degrees off. This group only varies by 1.1F. That’s fantastic. Haven’t tried them long-term, but off to a better start so far.
