Amazon.com Review
Conquer the limits of space and time with this cable-free radio-frequency thermometer from Oregon Scientific. Tuning in to as many as three remote units at once, this thermometer helps monitor the four corners of your kingdom from one base unit. The kit includes one remote sensor, which can be stationed up to 120 feet away and sends signals every 30 seconds. The main unit's LCD screen lets you assign a channel to each remote, and then scroll through the menu as necessary. You can also set temperature range limits, program alarms, and recall recent highs and lows at each location. A temperature-trend icon reveals whether temperatures are rising, steady, or dropping. The thermometer's base-unit range is 23 to 122 degrees F, while the remote sensor runs from –58 to 158 degrees F. Both units feature an optional Centigrade scale. Designed for the desktop or the wall, each piece of equipment requires two AA batteries. --Emily Bedard

Watch Out for them Fog Burns
Got this thermometer a few weeks ago and it's turning me into more of a weather geek every day!

I actually bought two sets so that I could have a remote in the basement wine cellar (remote #1) and one outside (remote #2). Both indoor displays are able to "read" from both remotes so I now can monitor the temps in my basement and outside from either the bedroom (display #1) or the office (display #2).

Every so often I'll lose the outside signal in the office but that's because the distance is probably reaching the 100' max -- not to mention that there's an entire house in the way -- but the signal returns after a while. The cellar remote signal has been stable from day one.

I can't really tell if the temps are accurate to the tenth degree but when I set the display units side by side and give them time to settle down they read only one or two tenths different. Not enough error for me to care since I wouldn't notice a tenth of a degree difference anyway.

Fun and entertaining gadgets for not much money -- man, can it get any better than this?

Fickle on range and set up
I love weather and have had several Oregon Scientific instruments and enjoyed owning/using them. This one I bought on clearance for [$] at a local department store. The read-out is great -- big, clear and crisp. My biggest criticism is that I got no where near the distance (90 feet, I believe) claimed to be possible between transmitter and receiver. This forced me to put the receiver (main read out unit) in a place that wasn't as convenient for me. Where I wanted to put it was maybe 60 feet away from the sensor -- well, well within its rated range. It would not consistently hold a signal for that distance. A secondary criticism is the mounting bracket for the remote sensor is of a fairly cheap plastic and I am still not able to really secure it to an outside post. In theory, it slips over a couple of nail heads or screws, but it is not doing that for me. It would have had helped had OS included a paper template to use for drilling the mounting holes.

If you look beyond these criticisms, the price-value equation is favorable. And guess what -- batteries ARE included -- four of them. What a treat!

One other huge advantage: Its operating range on the low end is very good, an important consideration if you live in cold weather state. I don't think it reads to minus 20, which sometimes occurs where I live but when it's that cold, I don't want to know it, either :) Also, this unit runs on regular batteries; some competitive units require very costly lithium batteries.

Great unit, great value
These units are great. We have several Oregon Scientific products and have been happy with all of them. They perform as advertised and are fairly reliable -- of 3 Oregon devices, I had to replace one after 2 years, but they're not very expensive so not a big deal.

The outdoor device reliably senses temp -- but keep it out of direct sunlight or the readings will be high.

It sends the signal to the base unit indoors over a reasonable distance and through a couple walls.

If you want to splurge, go for one of the devices that includes humidity and atomic clock et al.
