5 stars Very pleased with home weather station
This is second LaCrosse product we have had. This weather station model is more advanced than our first. It was very easy to set up and outside instruments easy to install. My husband loves everything about it. Home screen very easy to read. Wind speed and precipitation are on this model and my husband says is the best birthday present ever.

4 stars Looks great
I'm an old retired man. It sits on a post 15 feet from the house. Haven't had much rain lately. It seems to echo my other monitors. I had a nice rain going and the power went out. Lost the reading. I should put batteries in it. Neighbor is jealous!

5 stars Great Weather Station
I have always been a customer of AcuRite stations but their quality has turned to junk. I needed a new station and took the plunge for LaCrosse. This unit is super simple to install and connect to the app. My only negative comment is their display screen needs to be brighter. Where we have it located, on the exterior window sill, we can not see the display during the day since it is too dim. My son got the same unit for Christmas 2021. He loves the station and so do I. With the app we can keep track of weather conditions in both upstate NY and NC.

5 stars My husbands Birthday present is a gift to both of us.
YouTube helped get it up and running. Very impressed with this product. We have been looking for a weather station for a while now and we love this.

5 stars Working very well.
Was easy to set up and had it working within 20 minutes. Had LaCrosse before but with its connection to its app, it easily surpasses the earlier version. Only been working 3 days but impressive. Only drawback is that the receiver itself has to be plugged in. This reduces the places it can be placed!

5 stars Accurate, easy to use and set up
This is a great product. Took me little time to set up and use. I highly recommend

4 stars New weather station
Weather station looks and works well. The reason for 4 stars is I cannot get the wifi to work. I see many others have this problem. I will be contacting them to see if they can help. I have used Weather shack before and always had a good experience.
