Asian sensors, are they suitable for more than experiments?

For some time, I’ve been designing a small group of alarms for cars, motorbikes, and (very) small houses. I’m looking at using some of the low cost sensors sold for Arduino’s and Pi’s. The specific devices I’m interested in are:

PIR Sensor Module
ADXL335 Triple Axis Accelerometer Module
HC-SR04 Sensor Ultrasonic Sensor Module
RCWL-0516 Microwave Radar Sensor Module

I’ve made a few prototypes which are working well.
Does anyone on the group have experience of their long term reliability over several years?
