5 stars LaCross Weather Station
Works Great!! Like it so much a brought a 2nd one for another home.

5 stars Great information
Easy to install and immediately pleasing, this weather station is a winner. The display is awesome and the amount of data avilable is impressive. We added the rain guage but haven't had any precipitation to report accurately.

4 stars A very good up-date.
Perhaps the instructions could be a little more explicit on how to use. I am of the older generation. (over 70 that is) and do not understand this 'New" stuff. Product is very good from my stand point. Easy to set up and use. I'd buy it again.

5 stars Nice product
So far I am very pleased with this product. We wanted a simple weather station with just the basic weather data and this fits the bill. The display can be set up to provide exactly what you want -- for example you can set it for indoor temp or outdoor temp or to flip back and forth between the two. I like the added touch of the small solar panel on the sensor to keep the battery charged. The only thing I found lacking was the attachment hardware for mounting to a pole. There should have been U-bolts but they were not provided. No big deal. Overall I am very pleased with the unit.

5 stars Very easy to setup and program.
Weather Station initial setup was very quick and easy. I like that I am able to add more components at a later time.

5 stars Overall, mostly very satisfied.
I only wish it would record higher wind speeds, but that would only be very limited times.

4 stars Very pleased
This weather station was a gift for my husband. Easy assembly and set up pleased him So far, it is operating beautifully. I later ordered the rain gauge add-on but wished I had read more carefully and bought it with the station. Overall, we are both very happy with the weather station.
