Product review (5 stars): Excellent home weather meter
This unit was provided to me free of charge for purposes of review.

The WS-11 immediately exceeded my expectations. It's newest feature is a color back light which reflects the changing temperature with ten colors from HOT red to COLD purple. With the included AC adaptor the colors can be left on without fear of killing the batteries and in a power outage can be turned off and on at will to check current conditions in a darkened room. I am not easy to please and I can't say enough about how much I love this feature!

Secondly, the size of the station. At 4 1/4 X 5 in. (overall 5 1-4 X 7 in.) it makes the screen large enough to clearly see the numbers that matter the most.

The screen is divided into three distinct groups: The top has inside temperature in large display with the current days high and low in smaller numbers below. Right next to that is and identical display of the relative humidity. The middle portion of the screen displays the same information for outside.

About the outside sensor: The manual (you can download the PDF version from the Ambient web site even before you buy if you are a skeptic) recommends a shaded place for hanging, more or less in a location protected from a lot of water. However the sensor has a gasket on the battery cover and with care water should not be an issue.

The main thing is shade. Direct sun will give you a reading well above the actual ambient outside temperature, so pick your location wisely.

The last third of the screen sports an Icon which changes, literally, with the weather. Before I wrote this today it changed from partly cloudy to rain three hours before it started raining. Then you have the Barometric Pressure readout (you can pick relative or absolute), the date and a large graphing of, well, your choice of temp, humidity, and pressure.

To top it all off, everything is adjustable, you don't have to accept the factory defaults as gospel. One of the reasons I like the color back light is that one person's comfortable is another person's too hot or to cold. The color is adjustable so a pleasing color is a pleasing temperature for you. This is important especially where the Barometric Pressure comes in since this varies from place to place. If you read nothing in the manual about the various adjustments, read all about this.

There are things I haven't mentioned here, like the alarms you can set, but you get the picture - I really, really like the WS-11 and look forward to the day Ambient decides to make a version that can feed data into my computer to track trends. Do take the time and have the patience to read the manual and make adjustments over the course of the first two or three days. Initial set up is as easy as loading batteries and finding a place to hang the sensor and a place to hang, or stand, (it has a built in pull-out stand) the display.

Just hope they don't read this review and raise the price, its that good.
