I have posted a few times about cheap Chinese products. One of my recent free-international-shipping purchases was a replacement for a 4-port USB hub that was compact, highly-rated on Amazon, and, for whatever reason, disappeared.
After a week, its status.
Obviously a quality-control reject, it dropped connections. Fortunately, during its brief tenure, I did not rely on it for external drives, just keyboard and mouse.
So it’s a complete write-off, my investment of USD 0.99, delivered from China for free.
