## Description

This wall thermometer brings a secret with him. The front can be pushed upwards & offers on two hooks an ideal hiding place for keys. The thermometer shows temperatures in DegreeC & DegreeF from -30 Degree to + 50 Degree C. Packed in blistercard with euro-lock.

Review: Works great - This green version works much better than the white version. It slides us and down much easier. It’s a bit harder to read the temperature on compared to the white one. Although it is 3 times the price compared to the white version so far I think it is worth the additional cost.
Review: A Great Idea - Very Clever Idea. Please note that if it is placed in direct sunlight or exposed to rain -it will crack.

### ⭐⭐⭐⭐⭐ A Great Idea
*by T***R on September 27, 2017*

Very Clever Idea. Please note that if it is placed in direct sunlight or exposed to rain -it will crack.

### ⭐ Total cost $14.07. Not worth .75cents
*by B***D on September 14, 2021*

It looks like they melted down plastic army men to make this thing. It does what it says. It will hide your key, but it’s so poorly made that it’s almost conspicuous. Not what I’m after. I could buy a nice outdoor thermometer and tape a key to the back and it would be a better solution. Not secure. Didn’t come with mounting screws. Honestly think a strong wind would blow the top part off and reveal any keys inside. Plastic junk molded into a box with a thermo stuck in the middle.
