Love the quality of the barometer works perfectly.value for money arriving on time fit's in perfect with the surroundings

wonderful purchase for father. Loves talking about and checking the weather. Perfect gift!

Takes a while to adjust- I put it inside the freeze to adjust temperature and covered it with a wet clothe to adjust humidit. Pressure will adjust itself as it doesn't matter if it's inside or outside.

Brought as a present, very pleased with the quality and certainly the price. Our son was very pleased and the barometer now hang in pride of place. Many thanks

I was replacing a mercury barometer ruined by removal men. The new one looks ok but does not work at all . Very disappointing.
