Product review (4 stars): Time, temp and humidity work well. Do not purchase for a weather station.
I use this item in my RV while camping. So far the time, temperature and humidity sensors work well and appear to be very reliable. However, the weather station portion of the device is rather shaky. While camping for a week, the weather station predicted rain for two consecutive days that never occurred. So if using this device for time, temp and humidity it works well but the weather station is not accurate. Setup of the device could be simpler but if you follow directions it should only take a few minutes. The display is easily readable during the day and at night the large backlight button is accessible on the back of the device. I would have liked the backlight button on the front of the device but it's not a big deal to reach behind the display. The backlight is activated for a few seconds after you push the button and then automatically turns off. So far I've used one set of batteries since about Apr 2015 so battery life seems to be OK. Be advised, the device cannot be hung on a wall as the base is too wide and there is no hanger on the back.
