5 stars LaCrosse weather station review
Station shipped quickly and was well packaged. Easy set up, just had to get some C batteries for the outdoor sensor. Had a little trouble setting up the Wi-Fi with my router, but did get it connected. Working fine, nice display and like the mobile app!

Great product.Easy to install,little difficult to set time

4 stars Works as expected and fun to see from my phone
Again, I was only disappointed that it did not come with batteries, and I guess I missed where you recommend we buy batteries. It's just silly to receive a product you pay so much for and you can use it until you go out and buy batteries. Add $5-$10 to the price and include them!

3 stars The unit is excellent, although it is not user friendly.
I expected the V21 to be plug and play like the other 3 LaCosse weather stations I have purchased. I am still attempting to bring the atomic clock on line. The directions continue to lead the customer in a circle with no way to to talk directly.

5 stars It was a gift to someone else so I can't review it.
I will say I'm very impressed with your outstanding customer service and quick response. I would definitely order from you again!

5 stars Weather station
Very nice product, really needs to be plugged into 110 volt to see what a great product it is. Nice bright display, easy to read, I would recommend highly if your looking for a very nice home weather station
By Carl
From Georgetown, TX
3 stars Weather info is good but screen not up to par
The screen must be old technology as it is impossible to read at any angle, especially any distance. Indoor temp is hard to see even straight on at a yard or greater away.

2 stars Interesting, but disappointing
WeatherShack delivery excellent, product arrived on time with no issues! Oh the product, nicely packed and clean and crisp...then, once your expectations are heightened the downfall begins...WiFi, completely has to be 2.4g only, could not handle dual...Day light day savings, time zone, zip code, or anything dealing with NST is a joke, weather forecasting useless...
