QZQ Fish Tank Thermometer Aquarium Thermometer Wireless Touch Stick Digital Aquarium Thermometer LED Display ±1°F for Monitoring The Fish Tank Aquarium Temperature Accessories (Black)

Nice thermometer for my betta tank. The sticky tape holds extremely well. Seems to be very accurate. To save some battery, it stays off until you touch it, then shows the temperature. Perfect size. Shipped fast. Functions just as it should. Battery life seems long. Easy to use and install. Very good buy. I highly recommend 👌

So simple. Just peel and attach to outside of tank. Works like a charm.

Works perfectState of the art temperature Checking.Strong adhesive to hold with.

In comparison to the temperature setting of my aquarium chiller, this is within 0.5 degs of the chiller temp setting. So I'm guessing its working fine. FYI its not a constant temperature display, you have to press the button on the thermometer to show the reading. No big deal. Only issue is what to do when the battery eventually dies. Its mounted via a circular sticker on the back. You'd have to yank the thermometer off the tank to change the battery, and I'm not sure if it'd adhere after doing that. Didnt come with any replace adhensive.

Good thermometer for aquariums, works well, is accurate and is digital (easy to read) vs the mercury type. Battery is included, suction cup attaches to aquarium glass, easy to operate (tap it to read the temperature).

Accurate thermometer for an aquarium. Well packaged and very easy to install. Bright display with easy to read numbers. Display stays on for 10 seconds after you touch it.

Nice touch for my aquarium. Can quickly check the water temp. The included two sided tape really holds.

Perfect
