I Need A Good Thermometer Help

I got a digital one on Amazon and its anywhere form 1-3 degrees off. Can anyone suggest a reliable thermometer?

 

What brand is it?
I use the thermometers by CoraLife, they work fine for me

 

Zacro LCD Digital Aquarium Thermometer Fish Tank Water Terrarium Temperature I'll check out the CoralLife ones

 

That's what mine look like, but I would go with the CORALIFE ones, as they are the original makers of that thermometer.
There have been a few other companies that just used the same thermometer but rebranded it with their logo on the back, silly right?

 

Did you get them from Amazon? Are they accurate?

 

Yes, and they seem to be.
