VIVOSUN 2-Pack LCD Digital Aquarium Thermometer Fish Tank Water Terrarium Temperature Gauge with Suction Cup for Turtles Review

One of the items arrived with a broken LCD and the other broke 10 seconds after attaching the suction cup to the aquarium. The suction cup didn't hold up, it fell off and hit the stand, and there was a second thermometer. Both were also already on, and they have a power button that doesn't do anything when you press it. At least Revain got my money back, but don't waste your time. They also deviate from the actual temperature in the aquarium by a few degrees.

I put a thermometer on each end of my 75 gallon aquarium and found that there is typically a 0.8 or 0.9 degree (Fahrenheit) difference. Thinking maybe one of my heaters (one at each end) was mounted higher, I moved both probes together in the middle and found they didn't change. After giving them an hour to change when the temperature there was different, with the sensors literally half an inch apart, they read 78.8 and 79.6, so they're 0.8 apart, and who knows which one is correct (if any of…

UPDATE: The seller contacted me and sent me a new thermometer to replace the broken one. The new one works perfectly. Thank you to the seller for doing everything right and sending an item that works as it should. I appreciate great customer service! Original post: I don't know if the battery is dead or if the device itself is defective, but one of them doesn't work at all. Batteries were pre-installed and came with a working one. I thought I had saved some money by going for these instead of…

I bought this set of 2 because I have 2 tanks and wanted to upgrade to a more accurate thermometer. I used to use a thermal tape thermometer and it wasn't as accurate because the temperature of the glass doesn't match the temperature of the water. It gives a more accurate idea of what the fish are actually feeling, so I like it better! I put them in the same tank first to see how accurate they are and they only differed by 0.1 degrees Fahrenheit so I think that's pretty good! I found that the…

I was looking to buy a similar unit locally and saw it online and for the same price you get two in a pack! That in itself is a lot! Both devices worked great out of the box. Mine already had batteries and was on, although I assumed it was because it was tested before shipping (and hopefully no return). The suction cup was so-so at first and fell off a few times, but after settling into our home it is now taking root and holding up well. I used this in my daughter's 10g tank and the other is…

I have used other similar products to check water temperature in aquariums. This time I bought the product because it has a longer cord than other similar thermometers. However, I have confirmed that the temperature measurement accuracy of this product is very poor. It always read 4-6 degrees Fahrenheit below the actual temperature measured by some of the accurate thermometers I have. Based on my experience with this type of thermometers, I can agree that thermometers show temperatures 1-2…

First of all these thermometers were shipped already switched on although they have not been opened and do not appear to have been tampered with. There was supposed to be a plastic tab in the battery compartment that had to be pulled out, but there isn't. They also fluctuated constantly, reading different ambient temperatures from each other. It was the same when I put them in the same bucket of water. The suction cup on one was terrible, no matter what I tried it refused to stick. In the end I
