Beats the others price/set up, etc.
Extremely easy set up, smaller than I thought but still easy to read. So far no issues.

Works well
I have this set up for my attic. The receiver isn't particularly close, but I still get good measurements. The fact that it lights up when you touch it is a bonus. There is a mounting hole on the back of the receiver, but I purchased some magnets, and I will use those to attach this to my refridgerator. The instructions are clear. This unit does NOT interfere with my other wireless thermometers made by a different brand.

A nice remote thermometer but it is not waterproof
The wireless indoor/outdoor thermometer/hygrometer works well but it has two minor issues. According to the instructions, you need to place the remote sensor at a location that is protected from rain, which limits the sensor's possible locations. Also, the feature that tries to predict future weather using a barometer that senses changes in air pressure is not very helpful. However, as near as I can tell the indoor and outdoor temperatures are accurate, as is the hydrometer. One feature that I really appreciate is that lightly touching the top of the device will light it up for a few seconds making it easy to read in low light conditions. So accuracy is good and that is what really counts. But properly locating the remote sensor so that it will not be affected by rain, while it remains fully exposed to the outdoor temperature without being exposed to full sunshine during the day, can be a head scratcher.

Well worth the money.
Amazing little device so far. Will follow up. Two days later, it no longer works.

This is so fun!
We are a bit of weather nerds. So this has been fun. I purchased this just to play with. I’ve moved the monitors around different areas of the porch and rooms in my house. Pros, after a couple of days, it seems pretty accurate. The temperature’s agree with the outside temps on my weather apps and the inside temps agree with my thermostat. I just put batteries in and it was working. Very simple to get started. The back light with just a touch is wonderful and it only stays lit for a few seconds. I like that the light goes off quickly. The numbers are large and easy to read. I like that it’s light and portable. Con’s, it takes a couple of days to ‘settle in.’ I haven’t found any other cons. Especially for the price point, I love it. I may be purchasing an actual weather station soon!

Affordable and works as described
I have the thermometer inside a small room attached to the side of the house that houses our water heater and water pump. I can monitor the temperature from inside the house with this which makes it convenient and reassuring that everything is safely operating during the cold winter. I would recommend it to anyone who wants to keep track of the temperature anywhere you place the thermometer.

Great customer service
Excellent product and customer service. 18 months after I bought it the top temperature gauge numbers did not show due to some battery leakage (on my end), and they shipped me a replacement!

Smaller than unit it replaces (prefer this size, still easy to read). Appears to be accurate, and displays additional weather info such as dew point. Pleased with the weather station, would be nice if it displayed the time too.

It works perfectly fine, even in very low temperatures. Very accurate and precise. The display visibility is excellent and the brightnes can be adjusted with a single button, which is convenient in the dead of night to not have to fiddle around controls.
