Veanic 4-Pack Digital Aquarium Thermometer - Monitor Water Temperature in Fish Tanks & Terrariums

karen saretsky: Batteries don't last very long. To conserve Batteries you would need to shut them off between readings. I like to check mine randomly so that's a bit of a nucense.

S: I have got 2 packs of these for my aquariums. They work great. They might not be exactly correct, maybe a degree or 2 off but overall great product for the price.

Chad N.: I found that these were not super accurate, and unfortunately 2 arrived and wouldn't turn on. Very disappointed that only 2 worked.

When they arrived, i set the 2 working ones up in the same aquarium, and they were reading 76.4 and 72.6 on the same side of the aquarium a few hours later, after leaving them for a few nights, i came back to see they were at 75.2 and 72.2, still not as accurate as i need them to be. For the price point i was not satisfied with the quality of product i received.

Kristen Schnarr: These are reasonably priced and last, but all 4 read different temperatures.wothin several degrees F. I wish there was a way to adjust the reading to make them all the same.

Poor product: Not the most accurate and one had failed less than 6 months.

GSF: I put all four of these in my aquarium. They all were very close to the same. Nome were off 2 or 3 degrees. I'm cool with that because it's difficult to get a devise at this price to be 100% accurate. I'm happy with them and would recommend them. I don't know how long they'll last though. I may be able to come back and add to this if they malfunction soon.

Minty: If you have multiple tanks better to get multiple packs than buy at the store and get more because fish lovers will always get more tanks and impulse buyer you know who you are will need it. I used this for my fish tanks works good and accurate. Malfunction to one of the temp reading 93 degree fahrenheit, while 2nd temp readings were in 74-79 range in the same tank. Will buy again though.

Haylee: I love them . I have many different types of animals and it works for all of them .it’s great that it comes with multiple too. I’ve made sure and their all very accurate. It changes quickly to what the temperature is , also it’s small so it work well for large and small tank and if your trying not to take up much space in your tank .I highly recommend it.

Amazon Customer: These temp probs are accurate within +- .5 degree. I'm very happy with these. My only issue was getting them to stay attached. It takes 2 or 3 times to get them to finally stick. After that they seem to be holding. The suction cup in the tank has a similar issue. This was not a reason to not buy them. Just check the suction so the probe does not get dislodged by active fish. I'm very happy with this purchase
