4 stars Works great
The product data supplied with the unit is pitifully insufficient. If you purchase this, be sure to download and print the manuals and FAQ sheets so that you will be able to use and enjoy all the features of this weather station.

4 stars Like it just fine.
Does just as stated. But can't connect to WIFI if you use the RING security system. Not happy about that. Ring used a WiFi extender so can't spilt router between 2.4 and 5 ghz.

5 stars La Crosse complete wireless Weather Station
We love our new wireless weather station. We always know what the outside temp is, what the humidity is, date and time and all the other stuff that is on it!!! Love it.

5 stars Very happy with the La Crosse weather station and App.
I'm very happy with how easy the station, sensors, and iPhone app were to set up and get running. I stalled getting my iPhone to go to the 2.4GHz needed to connect with the station until I reread and followed your instructions and just moved the phone further from the WiFi router until the 5GHz dropped out. The app is very well designed. Being able to display graphs of temperature, humidity, wind speed, and rain fall is great and has increased my interest in weather. All in all, I highly recommend the La Crosse station and expect to add more sensors in the future.

2 stars Customer service lacking, product decent
The product seems to be operating well. Set-up was not too bad but when I called the AcuRite 800 number to get some verbal help, the person who took my call seemed both disinterested and rude. This would cause me to NOT do business with them in the future. You have to know how to "act right". But getting back to the product, it seems as if it is accurately reporting the data. I am not able to use the app because my Internet service is more up-to-date than the requirements for the V40A-PRO-INT. At the end of the day, I suppose I don't need yet one more reason to be looking at my doggone phone. The bottom line is, the product seems pretty solid here in the early going. I like having the ability to mount the temperature gauge in a couple of different places (thanks to the velcro mounting strips) to avoid direct sunlight from hitting it and driving the temperature reading up erroneously.

5 stars Great Display--Easy set up
Love that it may be mounted on the wall.

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.
