ok

It doesn't block a lot of the false alerts in town and so far the device doesn't remember them. Also I gave up on trying to figure out how to update the thing. You basically have to have a computer science degree from MIT to figure it out. Wish I bought the one that has Wi-Fi. Lastly 90% of the menu settings you will never use. It has 50,000 selections thats easily to **** up. All I use is Town, Hyw, and Auto. It still over all is a good detector.
