Good day my name is Tammy, I am from CA, not the first time I order from the company manufacturer DRSONO, ultrasound sensor, the quality is super! Works like clockwork! Every time, delivery is fast, to CA is usually 2 weeks is the maximum, and so in 5 days came the goods! Sales manager, too super, a girl, very, quickly responds, if any questions, will not leave you in trouble!
