This is a wonderful way to decide what type of clothing to wear to work each day. Takes the guess work out of it.

Works, but display combinations are restricted.

Comment:
This unit is reasonably constructed but has the following UI problems that cause it to be less than perfect:
1) Oddly enough, this unit links the 24 display on the clock to metric (C) readings. So, if you want 24/F, or 12/C, you are out of luck.
2) The base thermometer air inlet is at the center of the two buttons, but its appearance makes it look like a third button. Poor placement.

A Three Dog Night

Comment:
I just finished building three doghouses, each one complete with Hound Furnaces to keep the pups toasty at night. And just in time too. The temperature is dipping down below freezing now, and last year, everyone sold out of the Hound Heaters around this time. So the dogs slept inside in the utility room all winter long. Big hassle.
With the Hound Heaters set to around 70 degrees for the beagle, 65 for the golden retriever, and 45 for the german shepherd/chow mix, we wanted to make sure all three were functional each night before sending the dogs outside to sleep. So we bought the La Crosse base station and 2 extra sensors/transmitters from Amazon.
I used Velcro to attach the remote sensors/transmitters to the inside of the doghouses because I didn't want to fumble with the tiny screws and anchors provided. The pictures of the sensors are deceiving. They are actually very small devices, probably about the size of a credit card, but skinnier. Each one was mounted at about the same level as the dog's head when lying down.
The doghouses are about 75 feet from the kitchen window, but we get great reception everywhere in the house. No problems there. As for accuracy, that's still up in the air. Hard to tell. The first night, I had all 3 sensors side by side outside on the deck, and they were all within 1 degree of each other. But once mounted inside the doghouse, there are so many variables, it makes it difficult to gauge their accuracy; like the dead zone of the Hound Heater thermostat, the construction of the doghouses, whether the dog was inside or not, etc. To be honest, I don't need great accuracy, just enough to know that the dog isn't freezing, or on fire for that matter.
Overall, the 3 sensor setup is nearly perfect for our purpose. Very easy to spin throgh the 3 channels and check each doghouse. Fun too. I just wish I had an outdoor thermometer so I could know how cold it is outside. I guess I can leave the base station outside on the deck and use the indoor temperature reading. Still, I'm satisfied.

Does not do the basic job

Comment:
The first job of any thermometer is to deliver reasonably accurate and consistent temperature readings. The La Crosse Technology WS-9121U-IT-CBP Wireless Thermometer fails miserably. The base unit and remote disagree with each other by one to two degrees even when left side by side for several days. In addition to that problem, the base and remote also disagreed with existing, known-to-be-accurate thermometers by another 2-3 degrees.
It's an attractive design, but useless as a thermometer. I returned it after a week or so of giving it a chance to settle in and give accurate, consistent readings.

Time and temperature, indoors and outside

Comment:
Do you remember those old mercury-filled indoor/outdoor thermometers that we used to squint at, wondering if the temperature was really correct? Do you remember how the outdoor sensor used to get broken after a few years, usually by a window being lowered too hard on its sensor wire?
That's not a problem with this La Crosse Technology WS-9121U-IT-CBP Wireless Thermometer, a great little unit that displays the time, along with indoor and outdoor temperature, in either °F or °C. It's LCD digital display is clear and easy to read, and is split into three sections, showing the time, indoor temperature and outdoor temperature. The outdoor temperature display is updated about every 16 seconds via a 915 MHz wireless signal, eliminating the need for wires.
The base unit, or receiver, measures 4.66" high, 2.29" wide and 0.69" deep, and has the option of being mounted in its flat base (see the photos) or wall mounted... and they even include the screws and wall anchors. Setup of the receiver is simple, and takes just a couple of minutes once the AAA batteries (not included) are installed in the base unit.
The smaller outdoor sensor (Model TX27U-IT) is a simple rectangular transmitter, measuring 3.5 x 1.5 x 0.53 inches, and it has a small LCD to allow for viewing temperatures while outdoors. It also has a flat base that can be mounted outdoors in a variety of ways, or with the screws and wall anchors. And the sensor does come with a CR2032 battery, which they say will last about a year. The directions say that this can be placed outdoors up to 330 feet away. I tested it at about 250 feet away, and it works just fine.
During the setup I found one strange quirk: if you set the time to 24-hour mode, the temperature indictor switches to °C, and in 12-hour mode, it automatically goes to °F. I personally didn't find this to be a show-stopper, just a mild curiosity. Did a quick accuracy check to see how much difference there was between the base unit and the outdoor sensor, and after awhile gave up, as they seemed to be at most 0.6 °F apart, which is better than I expected. There's a MIN/MAX button on the indoor receiver unit so that you can see the readings for both indoors and outdoors.
Pros:
- It's very accurate.
- Just set it up and forget it - it works.
- Excellent instruction book, in English Spanish & French.
Cons:
- It can't predict the weather.
Did you want to monitor the temperature in other areas, such as a baby's room, a greenhouse and your back yard, but all at once? This particular La Crosse Technology Wireless Thermometer already comes with a single TX27U-IT 915 MHz sensor, as previously noted, and will accept a total of three 915 MHz sensors - two in addition to the original. This can be a problem if you're not sure what your looking for, as there are dual-channel transmitters that will not work with this unit -- RTFM!
There are a couple available here that will work with the WS-9121U-IT-CBP receiver. The La Crosse Technology TX27U-IT 915 MHz Wireless Temperature Sensor with LCD is the identical unit to the one that comes with this wireless thermometer. The simpler La Crosse Technology TX37U-IT 915 Mhz Wireless Temperature Sensor has no LCD display, but is weather resistant, and excellent for use in outdoor areas where exposure to the elements might be something to consider. The point is that if you want to monitor the temperature in up to three remote areas plus where the base unit sits, you just need to pick the right sensor/transmitter.
Must admit that it was the quality that I had found in the excellent La Crosse Technology BC-900 AlphaPower Battery Charger that heavily influenced my purchase of this product over others on the market, and it has easily lived up to my expectations.
Had tested a few of these wireless thermometers and temperature stations from various manufacturers, and found some to be complete crap. One of the good ones was the La Crosse Technology WS-9013U-CBP Wireless Temperature Station, which offers the date on the LCD panel and its time is updated by radio signal. On the downside its outdoor wireless (433.92MHz) temperature sensor has a maximum range of "up to 80 feet." And be aware that transmission through walls and/or heavy foliage reduces the range on all of these.
If you're looking for a reliable indoor/outdoor thermometer without getting into a full professional weather station, the La Crosse Technology WS-9121U-IT-CBP wireless thermometer is very hard to beat.
