2 stars Accurate
I gave it a 2 star rating for one thing alone. The instructions are almost non existent. All they had to do is explain how each device is a separate device that must be added individually using each individual devices ser# Every device in cluding the display itself must be manually entered as a different device. They don't say that anywhere in the manual and it took me a while to figure it out. I'm very adept when it comes to electronics/computers etc and this isn't my 1st weather station either, it is the most cryptic to decipher how to get it all working. Would otherwise give it a 4.5 start for accuracy.

5 stars Installation was easy, Works like a PRO it is
Set up was easy, readings came correct and right away. Internet connection went well and data excellent to read and store. Unit went through 2-3 inches of rain, snow, and some 40-50 mph winds in first week and data was right on.

3 stars Country of origin.
At the moment, the first week of operation, the unit is flawless. My single biggest complaint is that a company named after the great city of La Crosse, has the audacity to make their products in Communist China.

5 stars Very Happy With Purchase
Wanting a home weather station for a long time, I researched several makes and models and read many customer reviews. I have been extremely pleased with my new wireless station and it seems to be performing exactly as advertised. Be sure to follow the installation instructions exactly - I got ahead of myself and mounted one of the sensors too early. When it came time to scan the barcode, I had to take it down. My mistake. I chose to use the wall mount and was able to run the power cord through the wall to a receptacle on the other side; looks great. So, with only two weeks of use, I highly recommend this station.

Working well so far
By Cindy
From Hesperus, CO
5 stars I will get used to it
I had very little information on connecting to a phone, and no information on connecting to the "Weather Underground" intact the only information I got with this was how to put the batteries in it. I also sent a message to LaCrosse on connecting to a phone, and a week later they have not responded, I did figure the problem out, with no help from the manufacturer.
