MarinaMarina Aquarium Floating Glass Thermometer with Sucker, Transparent

Traditional method that will not go wrong like a digital version. Digital versions have let me down in the past or been extremely inaccurate so I would just get one of these, pop them in and you can’t go wrong. Accurate when checked against other methods, value for money & stickiness can’t be beat even after 1+ years. The ease of installation is unbeatable and can even be done by five-year-old. Performance and durability again is unbeatable as one year on, performing as well as day one and is still in mint condition apart from a little bit of algae - still doing its thing!

It works well and sticks to the inside of the tank.

I like this style of thermometer for my tanks, but the one thing that is frustrating is the sucker won’t stay stuck to the glass, although this is a little frustrating, the thermometer reads well and is accurate, you just have to catch it as it bobs around like a buoy, it’s durable, easy to install, great value for money and performs well and It’s appearance is ok in the tank, even when it’s bobbing

I haven't had it "calibrated" but I trust it's reading near correct. All I really need to know is that the temperature has changed too drastically.

It's accurate and works well. Good for the price you pay and good durability. Easy to install by sticking to the glass and it stays there most of the time. (My fish do like to move it sometimes though haha) Looks natural in the tank too!

Nice clear easy read thermometer. Sticks to side of take easily and if it does come unattached it stays upright and just bobs around.

Very fragile. Lasted 3 days before a fish broke it. However, the reading was very accurate while it lasted.

The media could not be loaded. Only negative feedback is if your eyesight ain’t great you might find hard to read .. but great value and does the job well .. I would buy again if I need to.

It's a good thermometer. It is cheap, accurate and easy to read. It suctions well to my little plastic tank. As some of the other reviews say, it's very breakable, so be careful. Mabey not the best for a tank with big fish as they could bump into it and break it. This would be dangerous because it contains red jelly like stuff that is toxic and could kill fish. They make the same one in plastic and I recommend it for bigger fish that could break this one. The stainless steel one would work too. I've been using the glass one for 2 weeks for my baby ramshorn snail. Overall, it's a really good product, just be careful not to break it.

Funziona bene ed è preciso (testato con un altro al mercurio e segnano uguale), per le persone che dicono sia troppo piccolo e non si legge, compratevi degli occhiali, io vedo perfettamente le tacche di riferimento.
