I Love this product it is so easy to read and use and is very accurate. The only downside is that with enough determination my 4 year old son was able to peel it off. He thought it was a sticker. He only was able to peel off alittle less than half, but it would not restick and would no longer read without being directly on the glass. I bought another one though and have had it for quite some time and so far so good.

Pros: Easy to read

Cons: Kids were able to peel it off of aquarium

im not sure how long it would last because it is thin, but it tells the temperature right

Pros: works well

Cons: thin

Works great, has never let me down when trying to reach the right mating temp.

Pros: Easy to see, easy to read

Cons: none
