First off, heed the warnings from the manufacturer: don't put these in locations where they can get heavily rained on, and don't put them in direct sunlight.

I purchased this sensor as an add-on to a LaCrosse Weather Station so I can monitor an additional location. I've had it for a number of months now. This sensor is located in the backyard, attached to a deck underneath an overhang so it doesn't get too wet.

I live in a part of the country where the winters are long and harsh. We've had temperatures below freezing for almost two months straight now, with a low of -15F so far this season, and this sensor is still working. If it makes it through May (the end of our winter) I'll be surprised. I'll post an update if I have any problems!

UPDATE: Sept 28, 2009 (9 months after original review above): This sensor lasted all winter and summer, despite having snow accumulate on the top during the winter and lows of -15F and winds of 80mph... amazing. Keeping my fingers crossed that I'll have as good of luck this winter too!

UPDATE 2: April 24, 2010 (16 months after original review): Sensor still going strong, and still using the original battery! Made it through another long and harsh winter. For the price and considering the weather this sensor has endured, it is an AMAZING value. If I wish to replace the indoor weather station in the future, I will definitely look for one that is compatible with these sensors.

UPDATE 3: November 17, 2010 (23 months after original review): I almost feel ridiculous coming back here to update on this product again, but this thing is still working. I just don't understand it! I noticed that the top sometimes has snow on top of it (yes, we just got 20" over the past week), so it isn't as well-protected from the elements as I originally thought... yet it is still working and still accurate! I can't believe that I am gushing over a $15 temperature sensor LOL

UPDATE 4: January 28, 2011 (25 months after original review): Well, the batteries in one sensor finally died last month. I replaced the batteries (old and new ones are Duracell Ultras) in both sensors and everything is working great again. On a side note: we had temperatures of -20F over New Year's weekend with wind chills of -51F (its ridiculous and true). Guess what? Outdoor sensor worked fine and was within 1-2 degrees of actual temperatures registered by others in the area using their much more expensive equipment. :)

UPDATE 5: December 14, 2011 (3 years after original review): They're still going strong!

This wireless temperature sensor works extremely well and is easy
to set up - but you absolutely must follow the directions exactly.

Range is excellent - but just make sure that some large object such
as a metal shed or a large oak tree is not in line-of-sight between
any of the transmitters and the receiver.

I am using 3 of these temp sensors with the 915 MHz receiver. One
sensor came with the receiver, and I just purchased two more, since the
receiver can display up to three different temperatures from three
sensors. However be advised that if you carry one or more of these
sensors out of range and the receiver loses track of it, you absolutely
must take the batteries out of all three sensors and out of the
receiver and re-initialize all of them. This is not a difficult step,
since I did it several times while playing around with the sensors to
see how much range they had - which resulted in the receiver losing
track of one of them.

When you first see the instruction booklet that comes with the receiver,
it looks daunting, but not to worry, since only a tiny part of it is in
English, with all the rest in other languages. Once the temp sensors are
initialized, then it takes only a few seconds to set the clock.

I read in other reviews that some buyers had problems getting their
receiver to respond to some sensors, but that is because the buyers failed
to properly re-initialize their units. Also be advised that if you buy
a display unit that receives transmissions at 915 MHz, then you absolutely
must buy sensors that also transmit at 915 MHz. Several of the sensors
that are sold by Amazon look alike, but not all of them use 915 MHz, so
carefully read the tech specs to make sure that both the transmitter and
the receiver operate at 915 MHz.

If its where rain can reach it it can quit functioning. As it is to be used outside how do you NOT get rained on. My first one died.

I was looking for a replacement transmitter and this product was recommended to me by Amazon.com to go with my La Crosse Weather Station - the picture on Amazon.com of the weather station is exactly the one I have - HOWEVER Amazon needs to update the picture - the one they have is a 433 mhz model - but this transmitter is for a 915 mhz model - SO - doesn't work with what I have. Bottom line - it may be just fine with the right weather station - but I wasted my money buying this because it doesn't work with mine. :(

This product was a replacement, and it works, but the temperature is about 4 to 5 degrees lower than the actual outdoor temperature. The original one we had always registered the correct outdoor temperature.

Bought this to replace one that was mounted too low and got fried when snow covered it. Works fine. The trick with these units is to replace the batteries in all devices that talk to each other at the same time. Change the batteries in this first, then the other device(s) within one minute. When the batteries get low they won't talk and if you don't change them in this order they will not communicate.

I bought this Lacrosse weather station in January 2011. The wireless outside temp transmitter failed in July 2011. These transmitters should last longer.

The transmitter was purchased to replace one which became inoperable after three months. The concept of having a remote temp sensor is great -- otherwise I would not have purchased a replacement -- but actual operation is something else again. There is no way to know -- no indicator light or other diagnostic -- whether or not the transmitter is actually working. So if the receiver is not displaying an output you are left to guess which component is at fault. Not good. The other issue I have with the transmitter is that it is advertised to transmit "up to 300 feet." Good luck with that. Mine is about 30 feet from the receiver and were still having issues with lost signals when the temps are low, causing us to have to reset the receiver. (Yes, the transmitted signal does have to penetrate a window, but unless both units are located outside -- a very unlikely circumstance -- the signal is always going to have to penetrate at least one pane of glass.) All in all, it's a OK unit, but that's about it. I just hope it lasts longer than its predecessor.

This was a replacement for one that came with a LaCrosse weather station. It worked for four years outside in Texas weather extremes. I really think that's pretty good. It's accurate, the battery life is really good and the range is good. No complaints other than it quit working after 4 years. Only $15 to replace it. Not bad.

The product came quickly and was easy to set up. I already have one sensor that quit working after a year and just needed to replace the sensor.
