ELECTRON OPT Electro-Optix WSII Optix WeatherStation II Thermometer, Clear, 6" X 10 3/4"

REALLY like this weather station. It's so easy to mount on a window, and remove and remount as needed. It's also so easy to ready because of the large bright colors. And I absolutely love having the humidity reading in addition to the temperature reading! And based on other readings I have set up at my home, it is quite accurate. Would definitely recommend.

Recently bought two of these (as well as the KleerTemp thermometer without the humidity gauge). Just like the KleerTemp thermometer only, this unit is easy to install and easy to read. And, just like the KleerTemp thermometer only, this version must be hung out of direct sunlight in order to give accurate readings. I tested the thermometers on both units against 2 other thermometers I know to be accurate. Both units were dead-on accurate. However, only one had an accurate humidity reading. The other was off by more than 10%. (The reason for deducting one star.) I went through the return process on Amazon's website and was immediately emailed a shipping label for return of the defective unit, no charge to me and no hassle. (The reason I didn't deduct more than one star.) That somewhat makes up for the disappointment, but since I had only a 50% positive result with the first two units, I'm hesitant to order another to replace the one being returned. I suppose, since Amazon has such excellent customer service and no-hassle return policy, it would be worth taking the chance. I believe I'll give that more thought before I do, though.

Sometimes all you need is the outdoor temperature and humidity. I had this same item on a window for about 10 years at 8,500 feet winter and summer in Colorado facing west. It worked perfectly all that time, but this summer I noticed that the humidity gauge wasn't working. Taylor makes good instruments but time and UV will kill just about anything. I have another facing east with just the outdoor temperature and it's more than 20 years old still working, still accurate. Once in place the only time you need to remove it is to clean the window and it replaces just as easily as the first time.

I live in the high desert where it goes from very hot to very cold. I have a full-on weather station mounted in my back yard. I placed these on a north facing bay window about 18 inches from my bed's pillow. It's the last thing I look at when I go to sleep and the first thing I look at when I wake up. It reads a few degrees cooler than the weather station because it doesn't get the sun and is in an open but shaded area. The humidity matches what the weather station reads.

I tried this in 3 different windows before deciding it's just not able to read the outside temperature accurately. It was off by 10-20 degrees in each window. I wanted it to work because it was easy to install and it was very easy to read.

Not very accurate, particularly the humidity gauge. It is nice and big, clear, and easy to install. The thermometer is fairly accurate and very easy to see. But the humidity is frequently off by 20-30%.. I don't see any way to calibrate the dial and their web site doesn't have any additional information.

I've had a few of these over the years and when I took the last one off, decided it was time to replace it. I would really rather not be without it. Easy to read and pretty much on the money. We have a huge kitchen window, so it doesn't take up much space or look out of place. I've never had one fall off. Highly recommended because of the humidity!

I've bought this product before & it arrived in perfect condition & worked well. This one came with the humidity dial off from the device. It fell off when I opened the package. I've glued it back on but it doesn't seem to work as well as the others ones. It would have cost half the price of the item to send it back so I didn't return it.
