Practical, fun and relatively accurate.

I bought occurs after seeing the Bosch equivalent (100) in stores. I thought good idea to find. The problems of isolation in my house of 10 years of age.
Result: at the beginning the whole family wanted to have fun with because .it really easy with light beam to target and evaluate the temperature at a point. Sounds a bit gun Star Trek.
Track a cold spot is really easy, an average area is advanced, genre middle of a wall and the laser then walks all around, when it turns blue = cold.
Regarding accuracy, it is first difficult but not impossible to target a specific point (eg a pipe). The result is sometimes surprising on certain materials such metal ....

With this device I significantly improve the comfort (and savings) in two parts.

Why do not we find this product in stores in France .... That's a riddle
