Product review (5 stars): Good for the price
I have bought four of these. I started with one to test the humidity in my caravan. I was so impressed I bought two for our house in Florida, one for the Florida room and one for the living room. Finally I bought one for a buddy who liked ours.

I have seen other reviews which say the humidity display does not work at all, perhaps the humidity reading may not be absolutely accurate (which I don't need anyway) but ours function well in that they read 99% on a rainy day and as low as 30% on a fine day.

The temperature readings seem accurate, they compare well with my old analogue thermometers and even with the mercury one on my innner wall.

I like the original unit which shows the time constantly rather than the newer one which constantly flicks between date and time but that is just a personal preference.

For just over $5 each these are a very good buy.
