Digital Stick-on Aquarium Fish Tank Thermometer

Pros: It shows the current approximate temperature clearly and directly. It doesn't need anything dangling inside the glass and there is no danger of a fish messing with it or it falling inside the water. The install is as simple as remove the glue protection in the back and placing it on the desired spot on the aquarium.

Cons: None, it does what it have to do.

Other: Must have for any aquarist.

Pros: very interesting thing. depending on etmperatury changes color in some cells. it's magic. well packed, the top layer covered with a protective film

Cons: very sorry that was too short, I want the whole scale, from -30 Celsius to +30 Celsius Then I stuck it on the window glass

Other: cool garbage which can be stuck on the aquarium. or any other subject. such as floor heating

Pros: Here are my PROs : ° No need for battery ° No need to put something "into" the aquarium ° Peel off the sticky part and stick it to the glass. ° Very cheap price.

Cons: Here are my CONs : ° The temperature is hard to read ° No instruction comes with it ° What colors says what ?

Other: It gives an idea of the temperature, but not a precise one. Cheap ==> good to ave anyway ;-)

Pros: This is a simple and cheap thermometer can be places outside the fish tank, in a terrarium or whatever you need a fast to check general temperature. It work plenty well and don't need maintenance (batteries). It work like a sticker so is a lot easy to place.

Cons: If you want the precision this is not the best choice but for the price and the target of this kind of items (fast check of temperature without the need of an low error delta) it's perfect. Seen how it's made and how it work, at this price mean an high charge for the seller/producer but if we look at the end user market, well, this is a lot cheaper than in any other shop.

Other: I wonder if soon or later we will see on dx similar products able to manage higher/lower temperatures.
