Bought three. They have all been fine-tuned using the Arduino Uno and the new Ping library. For a while they work perfectly, nice and stable, and then they fail. The first lasted 4 months. The second and third lasted less than 24 hours. Not waterproof. The rubber grommets around the transducers do not seal well. So basically worth nothing.
