PAIZOO Fish Tank Digital Thermometer Accurate LED Display to ±0.9°F Tank Thermometer Aquarium Temperature Measurement Suitable for Fish, Axolotl, Turtle or Aquatic

I used one of those cheap stick-on strip thermometers on my 20-gallon tank for about a year. It worked okay, but after upgrading to a 40-gallon and seeing one of these digital touch thermometers on a coworker’s shrimp tank, I decided to give it a try—especially since it was only about $10.✅ What I Like:Way more accurate than the strip ones. With this, I actually trust the temperature readings—super important when you're dealing with sensitive fish or shrimp.Easy to read and use: The touch display is quick to check with just a tap. I find myself absentmindedly touching it every time I walk by—it’s oddly satisfying.Good adhesion so far: It’s stuck on well for a few months now. It did fall off once, but I’m 99% sure that was my cat’s fault. There were some suspicious paw smudges and cat hair around the area…Clean design: It doesn’t clutter the look of the tank and is simple to install.⚠️ Minor Notes:The adhesive pad is decent but not industrial-strength. If you have curious pets (like mine), maybe keep it higher on the tank out of reach or reinforce with a backup adhesive if needed.Doesn’t have advanced features: Just a basic thermometer—but honestly, that’s all I wanted.💡 Final Thoughts:If you’re still using the stick-on strip thermometers, this is a big step up for just a few more dollars. It’s simple, accurate, and looks nice on the tank. Definitely worth picking up—especially for larger tanks where stable temperature is even more important.

Very nice. Small. And we're just a touch of the button I can know the temperature of the water. I feel at ease now. I've had it for months I don't know when I need to change the battery it's still going strong. Definitely a great Buy.

These are perfect for your aquarium. For months I've had a thermometer either inside the tank, falling off the glass or stuck like a strip of stick paper and inaccurate. These have been truly amazing. Easy to apply, easy to operate. I enjoyed this product so much, I purchased more for my friends and I.I'll let you know how the battery life goes.

I bought two of these one to use on each end of my 55 gallon aquarium. You touch the button and it lights up in a green LED. The temperature displays for just a couple of seconds and then it goes dark to preserve the battery life. They seem pretty accurate. They agree with one another. These stick on the outside of the aquarium glass.You can see it in the lower left-hand corner at the bottom of my tank.

Why did you pick this product vs others?:Works very well. I don't have to worry about cords or anything. I usually buy the corded ones and they just break too much, so I tried this product. I also accidently poured some water on it when I was doing a water change. It didn't malfunction or break, so I was impressed with that. Accurate readings with no hassle. Happy with purchase

Why did you pick this product vs others?:Very accurate and waterproof. Attached right to the outside of my betta fish tank.

Works great! Accurate as well.

We needed an external thermometer for our aquatic turtle 🐢 tank because:1. I personally don't like a lot of things inside the tank for her to mess with.2. Her 6 year old human needed something to easily read & something she could check often without disturbing 'Shelly'.This passed both of our requirements. After having had it for about a month, I can confidently say it's very sturdy & easy to read.The temperature is a little off from when I have checked it against an internal thermometer. But it's never been more than one degree.When it dies (because at some point all small self contained gadgets do), Will most likely just reorder this product if it's available.
