Best Weather Station Ever Among Lots of Others
This is THE best weather station! Have tried several others and have suffered as they malfunctioned for various reasons. This one is the single best one we have ever used. It has been flawless and right on the money from the beginning. Wish it were able to be bought a little cheaper but this is definitely one of those times when you get what you pay for. If you are looking for a reliable, accurate and bullet proof weather station, spend the extra few bucks and get this quality piece. You won't be disappointed.

Quit Working quickly
Bought this for my husband for Christmas. He didn't set it up until our first trip in mid-january. On February 4th it stopped working. Batteries were good and he did some trouble shooting to fix the issue but nothing has worked. Will not buy again and wish I had the seller's information to see if I could get a refund or replacement.

Good but has glitches
We live in an RV full-time and purchased this to, not only watch the humidity levels in the RV, but to monitor the temp in the underbelly of the RV where our tanks and water lines are to help avoid freezing. We have had this unit for about 9 months now and still use and rely on it exclusively for our indoor/underbelly temp/humidity information.The Pros: It has a good display that is clear and easy to read. It does have the ability to add up to a total of 3 remote transmitters so you can monitor temp/humidity in several places. Currently we are looking to get 2 additional to regulate temperature outside and in one of our storage compartments. The main unit will stay lit and display information with a dimming ability (for low light so it's not too bright) when plugged into 110 power. This main unit also runs off batteries if you don't want it plugged in, but then the display is turned off (to conserve the batteries) until you press the button on top to light and read the display. This works well for us when we're transporting to different locations and are disconnected from 110 power.The Cons: I'm not sure if it has to do with the steal beams in our underbelly or what but the remotes signal becomes difficult to pick up at a distance of more than about 15 ft, which is a bit frustrating when our bedroom is 25 ft from the location of the remote. I'd like to have the main unit in our room at night to be able to see the temps, but it will often show the "signal lost" icon or intermittently display the temps so I have to keep it in our main living area and get up in the middle of the night to be sure the temps haven't gotten too cold with the possibility of freezing. Second issue is the remote unit, at times, displays temps that I know are not possible. We are currently in an area where the outdoor temps are in the teens and single digits and I'll get a random reading saying the temp in our underbelly is 87 degrees, or, one time it even said 144. I've had the opposite issue in the summer when it would be in the 80's outside, it would read that it was 25 degrees in the underbelly. Thankfully this is completely intermittent and I just disregard it. Usually within a few minutes it will update itself and display the correct temps.All in all we will continue to use this product, but will keep an eye open for something with rave reviews and fewer glitches, should we need another unit in the future.

Great Gadget
Great gadget to have in an RV or at home. Bought extra sensors and attached them to my waste tanks to see if they got to freezing. Colorful display, easy to see except which sensor you are looking at. That icon is tiny. Once mated wirh the base unit the remote sensors are reading about 40 ft away.
