Close to ATL I think.
I've purchased a few of these for home and family friends and they've been really good, with the exception of last week when my own sensor array stopped working (installed in March 2024). Contacted seller via amazon and a new sensor array turned up 2 days later which I was happy with.
Good data, nice screen, easy to use, decent app and various integration uses.
I bought another, not sure who to give it to as an xmas gift yet!
I just stick my thumb out the window
