Ernest Sports ESB1 Golf Launch Monitor +Pitchfix Tool | $10

Works as promised

I used this for hitting into a net about 8 feet away. I tried positioning it between four and 6 feet behind me. I found the readings to be completely inaccurate. Nowhere near my actual distances. The iPhone connection was very slow. The actual unit responded well. If it were at all accurate I would’ve given it a good review.
