I got my Shake last week and it’s working great. I picked up the 6.5 quake 329 miles from me really well. People reported pickup the 7.8 Solomon Islands quake from thousands of miles away. I had too muck background noise to be sure if I could see it. I need to place the unit someplace with less environment noise. It’s picking up the fames in my PC case and it looks like lots of little quakes when the cats run around the house. #-o
