Sold under a bunch of different brand names. But all from china probably the same manufacturer. Instructions are *well you know*... translated rather odd.
Mine does read fps. I shot about five air guns That I had data on previously with my Oehler P35 and Pact 1. Data was pretty done close. I did have to be very careful to be straight on when I fired the pellets where I was getting velocity variations once I figured it out. It was very uniform.
I'm not a guy that lives or dies by watching coronagraphs so this is just a double check when i'm done tuning a gun to get a baseline before and after
Overall not about 30 bucks spent.
