Adie: Love it, super cheap for what you get. Is only 0.1 Fahrenheit off from my other thermometer, so I’m inclined to say it’s very accurate!! Setup only takes about thirty seconds lol, so very convenient.

Crystal: Using these on my tower gardens as the heat is high. They should not get wet but do, they should not be in the burning sun but I do yet they are still working!!!!! Just turn them on when I need. GREAT VALUE!!! As they are being used in extreme conditions.

mariamaria: Easy to use good suction, I’m not sure of the accuracy because I have another different brand set that reads 2-3 degrees higher then this product. It came with 1 battery in a lil plastic baggie. I’ve had it for about a month and a half now yes I’d recommend this product. Oh I’m using it for my axolotl tub while the tank is being cycled.

Jesse: People often forget to arrange reviews "By Newest." thus they don't get accurate feedback. These are all the same. I could have got 3 for the price of these 2, and 3 is what I needed. Reviews had me buy these. Heck I've been in the fish game for 30 years and had no idea one of these suction cups was meant to go inside the tank to hold the probe. I just use the lids whether my 20 long or 250 gallon. They are on 1 deg off from my Heaters, but then again who knows if my heaters are on par? It's all Chinese stuff. The range for my fish is about 10 degree - Parrot Fish, Oscar, Arowana pleco etc. Again so far so good and usually I get two years out of these LED Thermometers. I've tried them all. If you get a few months, it's a deal. They are just my double checkers anyway.

RumbatechRumbatech: I've had these less than 12 hours but they seem to be working perfectly. I have a huge fish tank with Bettas outside the glass sliding door in the living room. We love to watch them at night, but with the cold weather we have been having here in South Florida I put some foam insulation on the tank to prevent heat loss on the sides, and back. The bottom, top and front were still exposed, so I got an electric blanket to cover the top and front to prevent heat loss, and I stuck an Aiicioo 24 watt 18 x 8 inch Under Tank Heater pad to the bottom. I wanted to raise the electric blanket off the front so that we could watch the Betta and his 7 newborn 'kids', but I was hesitant because I wasn't sure how fast the cold weather would pull away the heat. I also have two immersion heaters in the tank, but with such a large tank I had doubts as to their performance in this cold weather. I placed the probe of one of the thermometers all the way to the bottom and got about 62 degrees Fahrenheit. I then placed the probe of the second thermometer near the surface, just over 12 inches from the immersion heaters and got 89 degrees Fahrenheit. I found it strange that the temperature at the bottom was...
