Build quality is acceptable - works nicely - measurements are repeatable. Trig pin has pull-up resistor to 5V, and Echo pin is push-pull, so i recommend using level conversion when interfacing to e.g 3.3V FPGA (Sensor did not work well with 3.3 supply voltage) Price/Function ratio is good, almost excellent.

I purchased 10 of these for several projects I am working on. At first I was worried because they were very affordable, I didn't expect much. Once they arrived, I could see the quality was fantastic. They are also very accurate, well exceeding my expectations. For anyone interested, I created an Arduino library for it and put on GitHub - https://github.com/dan-power/Arduino-HC-SR04
