OK temperature and humidity transmitter.

Works OK. No problems using this with my old Radio Shack base.

This has worked out great for me.  I get the temperature and humidity for inside the house, and for outside using the included wireless transmitter.  Very easy to setup too.  I just took it out of the packaging and put in the batteries.  It picked up on the time and date right away and set itself.  It also records the high and low temp. & humidity for both inside and outside.  But I would have liked an easier way to reset the highs and lows...or at least have it record what time and date this high and low occurred.  It was a great price though and I got all my moneys worth!  I also purchased another wireless transmitter on Amazon.com to measure the temp. & humidity in my attic space since we've been having a little humidity problem in there.  It also was very easy to setup with this receiver and I still got room for one more transmitter on this thing if I need it.

These transmitters tend to last about 4-5 years. This is my third one in about 8 years. It is a bummer to spend $30 every time but I have yet to find another base unit that projects outdoor temp but also has outdoor humidity on the desktop display. My desktop unit also lost is atomic timekeeping capabilities but again, nothing else has these features. So I just keep purchasing these when they konk out.

Works well. Temperature readings are not real accurate. More complex than what I wanted. Wanted a real simple manual 120 volt thermostat. Didn't need digital memory and hourly and or day settings.

Works as expected, great to be able to read range of humidity and temperature. I realize how dry my room has been, sleeping must better with increasing humidity

Works well. To change it from Centigrade to Fahrenheit, I needed the internet to find the jumper to remove. The remote sensor is not that practical. The sensor probably needs a longer wire connection and the display probably needs protruding legs to prevent it falling over or moving, and/or maybe a rubber suction cup for the same purpose. It would also be nice if the computer could read the temperature over the USB cord so that it could be read remotely over the internet.

Works nicely, easy to use.
Only complaint, no humidity sensor, just on/off switch.

Preliminary review. 6/14/15

Works out of the box. Needs batteries, 4 AA, which I did not notice when I ordered. Not a big deal but adds cost.

I set up the units side-by-side outdoors. After a half hour or so the temperature is different by 1 degree and just changed to match. Not bad. The humidity is off by 7% which I'm not too annoyed by; if the units are each off by a few percent (not in the specs, btw) then it could be true. All that said, what's really important is "How hot is it outside?"

So far, so good, I'm pleased.

I have 2 different humidity gauges, this one seems to register a little on the dry side. This is nice to have for my basement, I use it to set the temperature on my baseboard or radiator heater, they do not have a temperature setting. I get the room to the desired temp and them mark on the thermostat with a marker. The next time I turn the heat up, I have a good starting point.

I have 4 of these in total and all were registering within 1-2 degrees temperature wise and within a 1-2% deviation in humidity of one another.  I have no other units to compare them to, but they seem to measure the noticeable temperature and humidity increase in the back of the house.

Wish the temperature was the larger value to quickly see. Works fine for monitoring the temp / humidity in a terrarium.

I placed the sensor in my greenhouse, so I can glance at it for basic temps throughout the day. If you're looking for lots of information and detail, I'd recommend a hobbyist-grade weather station instead. I do wish it had actual humidity % on it, but you get what you pay for.

Nice little temp. gauge for indoor/outdoor and reasonable price.  Display is a little cheesy, but functional.

I wanted to check out for a year or so the temperature and humidity in our new home's crawl space.  This thermometer and humidity unit has a remote sensor that sends both temperature and humidity to the main unit.  This will work great so I can see what it's like down there with seasonal changes. It was easy to set up and the unit has been working fine.

Purchased two of these- both seem to be reasonably accurate in regards to temperature and humidity, at least when compared to other measuring devices I own. Response time to changes in humidity is fairly slow, although in my case this is not a problem (I am using them in humidors). The high/low readings for temperature and humidity are particularly helpful to ensure that there are no large fluctuations.

I'm pleased with the unit and the price, but be aware that this unit does not include humidity readings, and the range from the outdoor unit is not as good as another LaCrosse unit I used for years.  If you don't need the humidity reading, and you will be under 100' or so from the outdoor sensor, this is a fine unit at a good price.

works well...takes at least ten minutes of the ambient exposure to read correctly the Relative Humidity in percentage of the equivalent environ when saturated.
