These multi-purpose rubber phantoms are very durable. I’ve used them for over ten years. If you keep them clean they will last a very log time. You can use water for coupling, but if you use gel make sure to clean well after you’re done. When the gel dries, the rubber may have little cracks. The speed of sound is not 1540 m/s, but the position of the pins are adjusted internally to make the distance measurement correct.
