Essential for aquarium hobbyists

Floating thermometers are great because they don't take up space on the glass. This one is lightweight and the dial is very clear. Highly recommend for freshwater tanks.

Good for koi pond monitoring

I bought this for my koi pond to ensure the water stays within a safe range for the fish. It works well, though I wish the numbers were slightly larger for viewing from a distance.

Great visibility

The contrast between the white background and the black numbers makes it very easy to read even in bright sunlight. Lost one star because the suction cup option would have been nice too.

Decent but basic

It does exactly what it says on the tin. Nothing fancy, just a simple analog thermometer. It gets the job done for checking bathwater temperature for the kids.

Sturdy and reliable

We have had this in our spa for three months now, through rain and sun, and it still looks brand new. The floating mechanism is stable and doesn't tip over easily.

Perfect for my backyard pool

This thermometer floats nicely and is very easy to read from the pool deck. The temperature readings seem accurate compared to my digital tester. Great value for the price.
