Been traveling and have not revisited it...
It's definitely a learning experience, it's not as intuitive as you would think, and you have to set it up forward of the line by a good distance so that means a cold range if you are not alone.
I found the aiming posts have to be removed to properly register the sound, they can block the report. Also the window is a little smaller than advertised, in fact putting the boxes on a tripod and shooting off a bench appears to be better than setting up in the prone, but again, I need to test it further.
It was definitely not a drop it down, turn it on and be up and running, there is more effort involved vs the MagnetoSpeed or Labradar
