Nowadays China is capable of making good products yet QC remains an issue. They are reliable if they are thoroughly tested and well protected in the transit.
Our management is from Hong Kong. We do test each tube. We don’t ignore any defect seen. We don’t cut cost in packaging – the shock absorption inside the box is as important as a strong outer box. That make the tubes from us different from tubes directly from China.
Since year 2000 we ship out tubes internationally and tubes shipped out from us runs well in our client’s system.
