Nice bedside wireless in/out thermometer
Very easy setup, compact, easy to see with bright screen and big numbers, shows dewpoint which many in/out thermometers like this don’t have and no clock and date to clutter up the screen. I have enough clocks in the house. Good price too.

Customer service is great and the functionality is terrific. Highly recommend.
My original order for this item was a bust, it never worked. I returned days later and received my refund from Amazon. The seller contacted me, apologized for the failure and offered a refund. I explained that Amazon had already issued a refund. The seller acknowledged and stated that they hoped I would give Unni another try. I was impressed that they reached out and decided to try again, and I’m so glad I did. This is wonderful! My other little indoor/outdoor thermometer is nice and functional, but the option to light up the display is priceless and I love the humidity and index feature. The display is big and clear so that I can see it from several feet away (better when it is lit up) and it is very accurate. I’m very pleased with this unit and see that my first order was just a one-off defective unit. I thank Unni for caring about its customers’ satisfaction.
Shannon Burkett –
A definite bargain.
Original unit had a calibration issue and would not read indoor temperature accurately. The battery indicator icon on the weather station for the remote sensor showed new batteries at half charge even when replaced.The replacement unit is working great and very accurate. I would recommend this product.

Bright, Sharp Display
Very nice, bright, sharp display even without using the backlight. Backlight comes on for 10 sec. by just brushing your finger over the “light” symbol although you only need it if your room is totally dark. The high contrast display looks great and is readable in just about all lighting conditions.I really like that the sensor accuracy is +- .5 Deg. Most other weather stations are +- 2 Deg. and both units run just fine using rechargeable AA & AAA batteries which you really should use for the outdoor sensor at least. Lithium will handle the cold temp. much better than alkaline batteries.I stuck a small felt bumper over the High/Low mode button on the rear so now I can just push on the unit as it hangs on the wall to get the High/Low temp. readings for the day, this way I don’t have to remove it from the wall to push the button.Very happy with this purchase!

Protected cover for weather station sensor.
Great addition to the weather station. Attached to my ladder on back of RV with one sensor inside. so now I can monitor not only the outside temp with the sensor protected from the rain and have it permanently attached to the RV. Great value and very easy to use. Perfect size for housing the sensor.

Super Teil. Zuerstmal macht es was es soll, das ist schön.Positiv hervorzuheben ist die Batterielaufzeit, die ist nämlich lange. Läuft seit 4 Monaten und die Batterien sind jungfräulich wie die Mutter Marie.

Sehr schöne Wetterstation. Innentemperatur und Luftfeuchtigkeit stimmen sehr gut überein ( Verglichen mit einer anderen FunkmeÃstation ), aber der Sensor für die AuÃentemperatur, sehr sehr ungenau….. Schade
