5 stars Wonderful product.
Great product! Easy to set up and intuitive to use. I like it so much that I will likely buy a second one for our vacation home too. Super value.

5 stars Top Notch Customer Service
This was a Christmas gift for my 67 year old dad. He loves it!! It was easy for him to set up and use. But my main reason for the 5 star rating is the customer service. I love a company with good ethics and this one fits the bill. Product was delivered before Christmas and I followed the tracking. Long story short, it was stolen from my parents porch along with other packages. Called Weathershack to initiate the UPS investigation and (without asking) they insisted on sending my dad a new station (overnight!)!! I was overwhelmed. Fantastic company and will direct anyone to them!!

4 stars Fun & Functional
I enjoy being able, in one place, to see the "weather" inside & out. I glance at the screen as I am getting dressed and when I am going out. It is handy and interesting, not to mention useful. I received my weather station as a present and I am very pleased.

Super easy to set up and works great! Biggest fear is how it will handle hail.

5 stars Seems to work fine
We replace an Accurite weather station with the La Crosse. We had the Accurite for 3 years with no trouble, but when it stopped reporting rain amounts, we literally could not get any response from their customer service, not even a mailing address! Don't buy their stuff! The La Crosse was easier to set up, the display is excellent, and it seems to be reporting accurately. The fact that the temperature and humidity sensor is separate in order to allow it to be put in a shaded area results in a much more accurate readings. I would recommend this unit, and the service I have received from Weather Shack.

I like the unit. The display is easy to read and has a lot of info. Easy to install and set up. Like being able to check weather on my phone using the app.
4 stars Nice Product
I bought this as a Christmas present for my Father in Law. Just what I saw without taking it out of the package, it looks like a quality product.

5 stars Installation and use of V40-PRO
Very easy to set up, everything connected the first time and the WiFi set up was simple after I pressed the +/- together and then the unit prompted mr for my WiFi password. The app is not quite user friendly but Ince the sensors connected it gave me notifications to view them. On the negative side there were no screws to stop the wind/rain sensor from spinning on the mounting base but, I had one that worked and will go to the store tomorrow and get more.
