There were a few. That’s common reality, actually. For some items I did checks and fixes; the issues were handled on the ground in China. With some suppliers it was easy, with others harder. On one order, for example, the voltage stabilizers got tangled up — not really the factory’s fault, but one manager making a simple thing complicated. From thousands of miles away the client had little chance of sorting it. I dealt with it directly, including going to the supplier in person, and got it back on track. That’s the difference between someone on the ground and hoping it works out.
