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

NICE READOUT, ACCURATE RESULTS, GOOD VALUE.
Quick shipping, easy set-up, visible readout with easy backlight switch. Accurate temp and humidity readings, but hard to tell how accurate the graphic weather depiction is at predicting upcoming weather.

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.

Nice size, accurate info
The product seems to be working great so far. easy to set up and a nice compact size. Light is a nice feature in darker areas.

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

Indoor Thermometer works perfectly but Outdoor Sensor is off by 5-6 degrees.
Glad to finally have the Indoor Outdoor Thermometer. Gives the inside temperature perfectly but outside temperature is always 5-6 degrees higher than actual. Outdoor sensor is placed inside the open lanai and not exposed to direct sun so I have just accepted the temperature is off by a few degrees.

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.

Love this weather station. Needed. to replace an old one that was not reliable. This is a perfect size considering I don't have a lot of counter space. It is easy to read.

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.

Works as described. Easy to activate and change from F to C degrees.

The outdoor sensor didn't even last a year. Disappointing. However! The seller contacted me and gave me a full refund well after the warranty period. Excellent customer service.
