Aquarium Thermometer - Digital Thermometer with Probe and Suction Cup, Reptile Fish Tank Thermometer with Large LCD Display, Terrarium Water Temperature Test

Great little thermometer, doesn't take up too much room, ideal for a smaller tank.

Easy to stick onto the tank, simple to use, nice size display, accurate temperature recording. Well worth the money. Definitely recommend to anybody wanting to keep track on the temperature of their aquarium. Great for our tropical tank!

These Zacro digital aquarium thermometers are a handy addition to my tank setup. They’re simple to install — stick one where it’s easy to read — and the LCD display gives a clear, accurate temperature reading that helps me keep water conditions stable for fish. Having two in a pack is useful for checking different areas (e.g. near the heater and a different spot in the tank) to ensure the temperature is uniform, which is especially helpful in larger or deeper tanks. The small size means they don’t take up much space and don’t interfere with décor or flow. The only minor downside: the adhesive occasionally loosens if there’s a lot of water movement, so I sometimes have to re‑stick them. Overall, though, they’re a reliable, inexpensive way to monitor tank temperature — a good buy for any fish keeper.

These have been an amazing purchase for my mixed reef tank. The battery lasts around 6 months and it is always very accurate and reliable. The sticky cup is good but I never really used it for sticking on as I left it beside my tank. Very easy to read from all angles. A highly recommend purchase for your tank.

So far so good. Just set it up, it's been 30 minutes. Reading a similar temperature to the other side of the aquarium. Suction cups seem alright.

Works well in my aquarium. Discreet at the side (opposite heater) reads clear. Easy to use.

Great little accurate thermometer but is very untidy wires to look at when installing no way to make it look good on the aquarium otherwise would get five stars but the look is very important

A great value thermometer. Really easy to set up and use. We put ours in our aquarium and the wire to the probe is a good length. The suction pads on display and probe are good. The display is easy to read and flick between C and F.

El termometro es facil de usar, cumple su funcion correctamente.

Small yet does the job. Easy to use. Been my companion in taking care of my flower horn, to make sure that I am giving and monitoring the correct aquarium water temperature. I think this could be useful also when checking water temp in the bucket before you give bath to your babies.

Good functional device should include suction attachment so one can use it to stick to glass aquarium
