Skywatch Windoo 2

Worked 1 time. I had to restart the app and recalibrate more than 20 times

Edit: I've decided to edit my original review upgrading the Windoo 2 to 4 stars from 1 star. For some reason the Windoo 2 heats up at room temperature (72F) when I leave it on for a while. The temperature reading will creep up until it's about 82F. At that point the relative humidity reading is about 10% off. When I left it turned on outside in 58F it didn't heat up and maintained an accurate relative humidity reading. I don't have any idea why it heats up at certain temperature ranges. I guess the work around to it heating up is to use it for just long enough to get a reading. I'll be keeping this thing. It's very tiny and provides me with useful information for making giant bubbles.Original review: I'd really love to give this little jewel like device a great rating, but I can't. The thermometer is sometimes off by more than ten degrees F compared to a known accurate thermometer that I have and the hygrometer is about 10% off too (it reads low). I'll be returning it. It's a shame as I love the size and design. It did measure wind speed accurately.

First issues, if you have a case it will not fit so you will need a 3.5mm extender. This should have been included with the unit.Second issues, wind speeds need to be above 2.5 mph before the anemometer starts to spin.Third issue in the graph mode of temperature the WCT (The Wind Chill) will only read Celsius even when the unit is set to Fahrenheit. So if the temp is 73.8F The WCT is 23.2FFourth issue, it is a little bit of a power hog but this is expectedIf you have a sound problem with the extender, you need to remove the case and attach it without the case or the extender and then turn up then sound. Once this is done, it should now work with the case and extender. (Apparently the sound will not adjust with the my extender correctly)The software needs improvements; it need to have wind chill and heat index added to the page and a graph page that will display multiple graphs.Other problems frequent crashes (1 in 5) and also hangs on calibration (3 in 10) also loses connection from time to time (1 in 15) (IOS 7.1.2 App 1.0.1) Extender D & K Exclusive 3.5The Temp, Wind, and Hum readings are fairly accurate better than my expectations._______________________________________________________________________________Update 1.0.2 now has fixed issue 2 WCT (Wind Chill) is now reading correctly.
